Ashtray Illumination Connector
Pay attention to the correct contacting for the connectors of the ashtray illumination and label illumination for the ashtray cover. Remember to mark
the lines before disconnecting them and upon conclusion of the work, carry out a function check with the ignition switched on and the interior
illumination activated.
Carry out function check for other-make installations in the area of the center console (front or rear) and produce the original condition of plug
couplings. As a result connected work must be billed to the customer and must not be invoiced via warranty and goodwill.
Refer to SI54.21-P-0007A Malfunctions due to other-make installations.
Should vehicle electronics fail in any control unit with no corresponding fault entry, check for foreign parts in the interior wiring harness of the
vehicle. (Note example of TV enable module for COMAND APS NTG2 in Figure 1.)
Sample malfunctions might be:
^ Random unlocking or locking of the vehicle while driving
^ Temporary or continuous set off of the hazard warning system
^ Sudden rise in travel distance in the IC.
The presence of non-approved accessories will null and void any warranty obligations and material defect liability obligations, where the installation
of non-approved accessories has caused faults or damage.
Repair costs must then be charged to the customer and they must not be settled through warranty claims.

Clearcoat Paint Systems with Higher Scratch Resistance
Since June 2002, starting with the model 215, clear paint Systems with higher scratch resistance came into use. The changeover took place in the
following years and was completed by mid 2004.
From June 2002 up to 06/30/2010 with a few exception (see Table) all vehicles with a more scratch resistant clear paint system, are marked with a
"C" in front of the paint code on the model plate.
As since 2005 on all models only the scratch resistant clear paint systems are always used, the identification "C" is deleted as of 7/1/2010.
In the table below, the data for the production changeover and marking are once again listed for the period 2002 up to June 2010.
Special protection vehicles (Guard) were painted with conventional dual-component Systems up to 01/2005 The changeover to the new scratch
resistant systems took place in 02/2005. As of this time all vehicles are also marked with a "C".
In collaboration with all of our approved paint partners suitable paint repair systems have been developed for the new clearcoat paints with improved
scratch resistance and these have been approved after comprehensive on-road testing.
All the paint partners we approve have incorporated the repair instructions and materials to be used in their repair guidelines.
These can be found on the After-Sales paint technology internet page.
The paint specialists of these companies are also available to help you on site, if required. Please remember to ensure without fail, that only these
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

approved refinish systems are used for paint repair.
This also always applies to Mercedes-Benz service operations that out source their paint work to external paint operators.
These Mercedes-Benz service operations are responsible for ensuring that only the approved refinish systems are used.
The application methods have not been changed.
The plastic attachment parts continue to be coated with conventional 2-K-clear coats. In the case of repair we recommend the scratch resistant repair
systems for plastic parts.
The existing sanding and polishing process has been changed. These techniques for scratch resistant paint are described in the work instructions
AR98.00-P-0012A.
The process and auxiliary materials to be used and the required workshop equipment are specified in detail.
Training courses on offer
Please remember that our paint and polish partners offer a wide variety of training courses on repair materials and processes, which are normally free
of charge.
According to our knowledge the training capacities of the paint suppliers are underutilized. We therefore ask you to take advantage of the
qualifications of the paint specialists within the market. This is the only way of ensuring a smooth repair procedure, which provides customer
satisfaction with proven Mercedes-Benz quality.
If you have any questions contact your Technical Representative.

Design group 82.10 Exterior lights
Date 08-18-2010
Validity All vehicles
Reason for change Remedy revised and the new model series incorporated / Supersedes DTB T-B-82.10/334
Complaint:
Headlamps/front fog lamps leaking or fogged
Cause:
As the headlamp is cooling down, e.g. after switching off, in rain or when washed, air is drawn in and the moisture from the air condenses on the
headlamp lens.
The ventilation of the headlamps ensures that this condensation is dissipated again after a short period of operation.
If the customer complains about fogging that is not present at the time of the workshop visit, then this is condensation. For these reasons,
condensation is a natural phenomenon and does not indicate a defect or malfunction; warranty and goodwill claims with this complaint will be
rejected.
Remedy:
Remedy 1:
A defective headlamp can be identified as follows:
1. Check headlamps for external damage and also check for correct seating/locking of the caps.
2. If the headlamp exhibits external damage:
3. Remove/install/replace headlamp.
4. Check headlamp setting and correct if necessary.
Note:
If there is external damage on the headlamp or if the caps are not correctly seated/locked, there is no grounds for a warranty or goodwill
case.
Remedy 2:
Clearing fogged/condensed headlamps:
1. Drive the vehicle into the workshop and connect the exhaust extractor.
Note:
In dry weather (temperature higher than +15°C/+59°F), you can also treat the vehicle out of doors.
Do not perform an engine wash before the defogging test.
2. Start the engine and switch on the following lights:
a. Main headlamps and front fog lamps fogged: High and low beams, front fog lamps, hazard warning system.
b. Only front fog lamps fogged: Front fog lamps.
3. Leave the vehicle in this state for 40 minutes.
4. Switch off all lights and the engine.
5. Check the fogging; a noticeable reduction in the amount of fogging must be visible (progress of defogging process).
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

Note:
If no reduction in the degree of fogging is visible, the headlamp is defective and must be replaced.
It is not physically possible to defog the headlamps completely.
Fogging does not impair the operation or the service life of the headlamp.

Interruptions in Radio-Operated Vehicle Systems
In the frequency range of the transmitter key or KEYLESS-GO, many other radio-operated Systems can also be transmitting and with a stronger
signal. Systems such as, radio frequency headphones, radio thermometer, garage door opener, alarm systems, etc. can prevent or interrupt unlocking,
locking, and engine starting via a KEYLESS-GO.
Fortunately, in parallel with radio remote control, most MB vehicles also have infrared remote control, so that even with radio disturbance, the
transmitter key will unlock and lock at short range. Exceptions are the 163 and the 170 as they do not have additional infrared remote control, but the
mechanical key will always work.
Advise customers that taking a vehicle key is always recommended as it is conceivable that a criminal might use a radio interferer to block the
locking of a vehicle. Locking is ensured by 3-signal flashing.

Malfunctions Due to Other-Make Installations
Recent attempts manipulating vehicle mileage through the use of third party electronic devices installed on Mercedes-Benz vehicles are being
reported.
There are several CAN manipulation devices on the market. Be particularly aware of two devices which are installed in tandem with the instrument
cluster or the EIS (Figure 1) and a circuit board which can be installed directly within the EIS (Figure 2).
If vehicle electronics malfunction, control units display implausible mileage readings, or malfunctions lack corresponding default entries; check the
vehicle for non-factory hardware. These are often installed in the interior wiring harness of the vehicle. Another example would be the TV enable
module for the COMAND APS NTG2 in Figure 3.
Possible malfunctions are:
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

^ Random unlocking or locking of the vehicle while driving
^ Temporary or continuous hazard warning system activation
^ Sudden mileage increase in the IC
If there is evidence that the vehicle has been tampered with (mileage altering device, aftermarket installation etc) please provide as much supporting
documents (pictures, test results, etc.) and send an email with the supporting documents to the Warranty Services Group and request that the vehicle
be put on warranty status.
Warranty will determine the correct status to be applied (usually status 8 which requires AOM review before any repairs are performed), file the

Uprated H7 Bulbs
The new uprated H7 bulbs are available. They have approximately 80% more light and approximately 30% more road surface illumination for high
beams compared with standard H7 bulbs. Due to the brightness difference between a standard H7 bulb and an uprated H7 bulb, bulbs must be fitted
in pairs when installing for the first-time; i.e., left and right headlamp. If an uprated bulb fails, replace as a pair as it is likely that (as an example); if
a left headlamp fails, the right may follow.
The new bulbs can be recognized by their chrome-plated lamp cap, and they can be installed into all H7 halogen headlamps. The set with part
number A 000 998 00 07 contains two uprated bulbs.
The standard H7 bulb N 400809 000007 will still be available.

Electrical - Electrostatic Discharge Damage Prevention

Date: March 23, 2011

Order No: S-B-54.00/238

Group: 54

SUBJECT: MY-All, All Models

Preventing Damage to Electronic Components Due to Electrostatic Discharge

Warning!

Every contact and each physical separation of material or any movement of solid substance, fluids or particulate loaded gases can generate

electrostatic charges. Plastic generally produces the highest electrostatic charge.

The following electronic components listed as an example can be damaged by ESD:

- Airbag components

- Control units, in particular their bus connections: Control Area Network (data bus/CAN bus) (CAN), local interconnect network (LIN), etc.

- Sensors

- Antenna amplifier

- Receivers and displays (Radio, TV, GPS, telephone, etc.)

- Multifunction antenna assembly

Safety precautions:

- Avoidance of contact with electrostatic chargeable materials such as PE, PVC, Styrofoam.

- Use only original packaging or specially labeled and defined packaging and transport materials.

- Electronic components which have been removed must be put down on an ESD workplace. (Example: when swapping the painted cover from one

multifunction antenna to another, this must be performed on an ESD table mat (000 589 52 98 000).

- Touch connectors on electronic components and wiring harness on the housing only. Do not touch the pins and contacts!

- Electronic components must be installed before they are connected so that potential equalization with the body can take place.

Returning electronic components in warranty and goodwill cases:

When returning electronic components it is absolutely essential to observe the procedure and safety precautions listed in WIS doc.

AH54.00-P-0001-01A. Electrostatic charge or discharge means the original fault can be falsified or overlaid. This can lead to distorted faults

symptoms in the case of the fault analysis of the component concerned.

SUBJECT: MY-All, Models All
Checking Components for Bolted Wheel Connection
Incorrect installation of and/or incorrect contact surface cleaning methods of bolted wheel connections can lead to the loosening of the
wheel-and-tire assembly, which can result in injury to people, property, or the environment.
To avoid this the wheel-and-tire assembly must be fitted following all operation steps that follow.
Procedure
A. Cleaning
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

1. Remove lubricants and soiling, such as oil, grease or sand from the following components:
^ Contact surfaces
^ Joints and centering on disk wheel
^ Wheel hub
^ Wheel flange
^ Brake disk
^ Brake drum
^ Spherical caps on disk wheel
^ Thread and radius seat of wheel bolts
^ Thread for wheel bolts and in wheel hub or wheel flange
2. Remove corrosion with a wire brush or emery cloth.
3. Clean any contaminated threads. Remove all corrosion and dirt from corroded threads using tap. There must be no damaged or missing threads.
Any dirt left in the thread prevents reaching specific torque value. The cleaned contact surface should look like Figure 4.
B. Inspecting
1. Check the following for damage:
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

^ Contact surface, joints and center on disk wheel
^ Wheel hub
^ Wheel flange
^ Brake disk or brake drum
^ Spherical caps for deformity and rim flanges on disk wheel
^ Threads and radius seat of wheel bolts
^ Thread for wheel bolts in wheel hub or wheel flange
2. Replace wheel bolt or wheel flange if thread is damaged. Replace disk wheel, wheel flange, brake disk or brake drum if damaged.
3. Check radius seats of wheel bolt for signs of damage, scoring marks and material deposits. Replace any wheel bolts that are damaged, scored, or
have material deposits. Any remaining sizing marks or material deposits will prevent reaching specific torque value.
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

4. Apply corrosion protection. Apply a thin coating of long-life grease as corrosion protection to the marked area of the center hole guides (see
arrow, Figure 7) on the wheel hub, wheel flange, and wheel contact surface. Do not apply grease or any other lubricant to the threads of wheel bolts,
wheel hubs, wheel flanges, or wheel studs.

Use of E10 Fuel
All Mercedes-Benz vehicles and Maybach, and AMG with spark-ignition engines can be run on E10 fuel.
Exceptions are all models produced at the factory without a controlled 3-way catalytic converter or models equipped with a carburetor. These are
generally older than 25 years.
The following table lists all models that may not be operated with a bioethanol admixture of more than 5%.
These models must always be run on gasoline of the grade "Premium or Super Plus sulfur-free as per DIN EN228 (2208 - 2011) or E DIN 51626-1
and other ISO or ASTM standards" or a comparable quality with the special designation Contains up to 5% bioethanol".

Note:
Mercedes-Benz and Maybach vehicles may only be filled with standard fuel qualities (DIN/EN specification). The octane number recommendation
(RON) for the particular engine type or age of the vehicle must be taken into consideration.
Note:
Grades to use are identified on gasoline pumps as: Contains up to 5% "bioethanol". The RON grade that is available as an E5 is at the discretion of
the fuel provider.

Assembly of Suspension Struts and Shock Absorbers
The correct procedure for installing and removing or disassembling/assembling shock absorbers and struts is described below.
1. Damper tube
2. Piston rod
a. Friction marks on sealing piston
b. Without friction marks on sealing piston
Procedure
1. When releasing or tightening the nut on the piston rod (Figure 1) (2) a impact wrench/driver must not be used because the piston rod (Figure 1) (2)
will also turn and by doing so it may cause friction marks (arrow) in the damper tube (Figure 1) (1) and on the sealing piston (Figure 1) (a).
2. When releasing and tightening, the piston rod must be counter held at the upper end using a suitable tool. See WIS document:
Disassembling/assembling suspension struts AR32.25-P-1018*.
3. Turning with the impact wrench/driver creates chips, which are deposited in the sealing piston and damage the piston rod sealing. In this instance,
the damper sealing capability is no longer sustained.

Handling Multipole Rings
When repairing and maintaining operations on the rear axle, ensure that there is no mechanical and magnetic damage to the multipole rings on the
external ball joint of the drive shafts, and that all work conducted is performed in accordance with the WIS documentation specifications.
To avoid magnetic damage to the multipole rings everyone who comes into direct contact with the components must familiarize themselves with the
following specifications for handling multipole rings. This applies to the following components:
^ Drive shaft
^ Steering knuckle/wheel bearing
^ Spring control arm
^ Transverse control arm
^ Cross strut
^ Torque strut
^ Thrust arm
^ Camber strut
^ Shock absorber
^ Spring
Note the following precautions when handling these magnetic multipole rings:
^ Do not bring into contact with external magnetic fields (Figure 1) (a).
^ Avoid damaging rubber-lined encoder track (Figure 1) (b).
^ Avoid soiling parts (Figure 1) (c)
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)

^ Do not bring into contact with metal shavings (Figure 1) (d).

Shock Absorber Replacement
General Information on Shock Absorber Variants
Do not replace both shock absorbers AIRmatic, ABC, ADS or adjustable suspension strut if only one is defective. Only a component that has been
diagnosed to be faulty (damper or suspension strut) may be replaced!
Noise Inspection
Reason for the noise should be determined by driving each side of the vehicle in turn over appropriate road surfacing or if possible by swapping over
the left and right component (damper or suspension strut). Before any replacement is made loosen and re4orque the corresponding
damper/suspension strut first and check whether this resolves the noise complaint.
Front
On the front suspension struts or dampers this need only be carried out on the top bearing mounting.
Rear
Both the upper and the lower attachments for the rear suspension struts or dampers must be loosened and then tightened again to the specified torque
with the vehicle in its ready-to-drive condition (i.e. the vehicle must be standing on its wheels).
Section 2: Special considerations for different damping variants
1) Air suspension struts and dampers (Model 164, 166, 211, 212, 219, 220, 221 240, 251)
ADS suspension strut (Model 129, 210, 140)
Adjusting damper (Model 204, 207, 231)
Since it can be assumed that a new shock absorber installed in a high-mileage vehicle would not harmonize with the used shock absorber and thus
impair ride comfort or vehicle dynamics, we recommend replacing these parts in pairs after the component has traveled at least 80,000 km.
2) ABC suspension struts (Model 215, 216, 220, 221, 230) In contrast to the air Or ADS suspension struts or conventional dampers, ABC
suspension struts must not be replaced in pairs at higher mileages (more than 80,000 km). The vehicle body dampening is performed by active
actuation of the plungers. These work wear-free! Passive wheel damping by the shock absorber integrated in the suspension strut plays a subordinate
role.
3a) Conventional dampers (Model 164, 166, 168, 169, 171, 203, 204, 207, 209, 211, 212, 218, 219, 230, 245, 246, 251) Since it can be assumed
that a new shock absorber installed in a high-mileage vehicle would not harmonize with the used shock absorber and thus impair ride comfort or
vehicle dynamics, we recommend replacing these parts in pairs after the component has traveled at least 80,000 km.
3b) Conventional dampers (Model 124, 129, 140, 163, 170, 201, 202, 208, 210, 461, 463) On these models diverse shock absorber variants are
standardized in the parts sector.
If dampers with new standardized part numbers are installed for replacement, then conventional dampers must be replaced in pairs!
In the event of any complaints on parts that have already been replaced in pairs, then the procedure as described in 3a should be followed.

Section 3: Deviating procedure
Information on additional deviating specifications for technical modifications is available in EPC and TIPS The current documentation in advanced
systems such as TIPS and EPC must always be followed! At this moment in time, we would like to draw your attention to the special considerations
for models 204, 207 and 212.

Topic number LI42.20-P-052990
Version 1
Design group 42.20 Parking brake
Date 01-17-2012
Validity Model 204/207
Reason for change
Complaint:
Squeaking, scraping or rattling noises from area of rear wheel brake without brake actuation.
Attachments
Cause:
1. Brake shoes of the parking brake touch the inside of the brake disk bowl in the axial direction.
The brake shoes of the parking brake are fastened to the cover panel with retaining springs. These retaining springs must be centered on the
elongated holes in the brake shoes. If this is not the case, the affected brake shoe may touch the lip of the brake disk bowl in the axial direction
and cause noises (see attachment 1).
2. Stator clip has slipped and touches the inside of the brake disk bowl in the axial direction.
A stator clip is pushed onto the support for the brake shoes of the parking brake (brake stator). This prevents the brake shoes from working
into the aluminum wheel carrier. If this clip is pushed too far on during assembly, it may be widened in the radius area of the brake stator (see
attachment 2, item 3). This widening means that permanent secure fastening of the stator clip is no longer guaranteed and it may wander from
the brake stator in the axial direction until it touches the lip of the brake disk bowl.
3. Expansion lock has play.
The expansion lock is designed to have sufficient component tolerance to guarantee proper functioning of the parking brake even when
covered with brake dust deposits in the course of operation. This play can cause rattling noises on rough roads.
Remedy:
Re. 1. Brake shoes:
Replacement of the silver-colored brake shoe retaining springs installed as standard for black retaining springs (see parts ordering note).
When installing the retaining springs, the following points must be observed:
^Use of installation tool W 112 589 09 61 00 (see attachment 3).
^ Insert the retaining springs through the cutouts in the rear axle shaft flange so that they can be mounted vertically on the brake shoes (see
attachment 4).
^ Center the retaining springs on the elongated holes in the brake shoes (see attachment 5).
^ To hook up the retaining springs in the cover panel, turn them counterclockwise (to the left) to prevent tilting and to avoid stresses.
Re. 2. Stator clip:
Check the stator clip for abrasion marks and correct seating on the brake stator (see attachment 2, item 1: The sides of the stator clip must be
flush with the brake stator). If abrasion marks are visible on the stator clip, or if it is installed incorrectly, the stator clip must be replaced.
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)


Re. 3. Expansion lock:
Install an additional snap clip between the extension spring and the expansion lock as per the installation note (see attachment 6, Figure 1).
When installing, please not:
^ Position the snap clip in the center of the extension spring and make sure that it engages properly in the extension spring (see attachment 6,
Figure 2).

Parktronic Malfunctions and Faults
This is an overview of Parktronic malfunction and fault scenarios, respectively.
Malfunction Scenario 1
Malfunctions are indicated with double red (4 LEDs) warning elements and no warning tone (Figure 1).
An entry is not saved in fault memory.
Malfunctions can be triggered by external ultrasonic signals:
^ Compressed air
^ Drier blower for a washer system
^ Rail vehicles
^ Brake squeal on vehicle or a nearby vehicle
Or through:
^ Soiling of sensors with ice or snow
^ License plate brackets
Fault Scenario 2
Faults are indicated in the Parktronic warning elements with double red (4 LEDs) with warning tone (Figure 1) (see arrows).
An entry is saved in fault memory.
The sensor function is automatically checked while driving at between 22-37 mph. If a fault occurs when driving, then this is issued at a speed less
than 9 mph with double red lights and warning tone.
The following applies to both scenarios:
If a malfunction or a fault is present for more than 2 seconds, the display in the warning elements goes out and the PARKTRONIC OFF button in the
UCP lights up in red.
Diagnosis

Mercedes-Benz HVAC-Foam Cleaner - Work Procedure
NOTE:
This procedure is not approved for vehicles covered under warranty. Refer to LI83.00-P-051588 for details on which vehicles can be cleaned under
warranty using Mercedes-Benz Contra Sept disinfectant cleaner (S-B-83.30/134). Additionally, the combination filter is a maintenance item and is
not covered under warranty.
Procedure
1. Start the engine with the A/C ON, temperature set to coldest setting, inlet set for outside air (not recirculate) and blower set for high speed.
Note:
The A/C must be run for at least 15 minutes to get condensation to build on the evaporator. This will adequately wet evaporator and promote the
product's ability to clean.
2. Locate the evaporator core case and blower assembly by removing any covers below the instrument panel on the passenger's side that may cover
the case.
3. Remove the cabin air filter and close off the empty filter cavity with the filter block off plate
^ For models where the filter bock off plate is integrated with the filter media (as with model 204/212). Remove the filter media, leaving the
bare block off plate, which can be reinstalled for the cleaning procedure (Figure 1).
4. On vehicles with an activated charcoal filter, remove these filters as well.
5. Drill a 3/16" hole in an accessible location between the evaporator core case & blower assembly, depending on your vehicle model. Use a drill
stop set at the thickness of the case to prevent plunging into case too deep.
Warning!
Follow the diagrams for a given vehicle model series, otherwise damage to the evaporator may occur.
^ Only drill through the case skin and gently probe inside with a dull instrument for any obstructions that the nozzle may encounter. If needed, use
the supplied plug and find another spot to drill.
2010 Mercedes Benz C 63 AMG Sedan (204.077) V8-6.3L (156.985)


6. Shake the disinfectant product can and with the hose attached to the can push the nozzle into position & rotate so the pointer faces the evaporator
core (Figure 2).
7. With the blower still on, start dispensing the foam in short bursts. As the case fills with foam, airflow will decrease from the vents. Pause for the
blower to push the foam through the core. (If the fan starts to squeak, stop dispensing while the blower catches up). As airflow resumes, continue
with short bursts of foam. If the system is overloaded by dispensing the foam too quickly, foam can escape from components under the dashboard.
NOTE:
Do not allow the foam to drip to any electronic components. Intercept any escaping foam with a towel.
To prevent possible staining, do not allow any foam to blow out of vents onto seating or other interior materials.
8. Continue with this application method until the can is empty then shut the system off completely.
9. After a minimum 10-minute wait, turn the blower on LOW to MEDIUM for 2 minutes to push excess foam out of the core.
10. Check that the drain is flowing freely under the vehicle. If there is no drainage, the drain is clogged. A clogged drain must be cleared.
Condensation will rinse out any remaining cleaner residue and contaminants.
11. Reinstall new cabin filters and activated charcoal (if equipped).
NOTE:
It is required that you replace the cabin filter after treatment. It is recommended that you replace the activated charcoal filters (if equipped).
Additional instructions for this procedure will be available via Learning & Performance:
VILT Course Code:X0001F-US.TTA (starting in second quarter 2012).

Driver or front passenger seat belt can only be pulled out with great effort.
Topic number LI91.40-P-047183
Version 4
Design group 91.40 Seat belts, emergency tensioning retractors
Date 04-05-2012
Validity Model series 204, 207, 212, 218
Reason for change Damage code updated
Complaint:
Seat belt can only be pulled out with great effort. At the same time a noise can be heard from the reversible reel tensioner gearing.
Cause:
The customer continuously pulled on the seat belt strap while adjusting the fit of the belt after buckling up (to reduce the slack). This caused the
drive of the reversible reel tensioner to remain engaged.
Remedy:
Insert the seat belt into the belt buckle with increased effort and switch on the ignition "circuit 15 ON". This causes the belt adjustment sequence to
be repeated and the drive of the reversible reel tensioner disengages properly. On customer request the "belt adjustment" function can be deactivated
using the multifunction buttons on the steering wheel. See operator's manual "Switching seat belt adjustment on and off".
Do not replace the seat belt!
Update the software version of the left and right reversible emergency tensioning retractor control units using XENTRY (Star Diagnosis).

Reason for change

Complaint:

COMAND (A40/3) and central display (A40/8) switch on without obvious cause with vehicle locked. The system runs and can be operated

normally.

This complaint only occurs on COMAND (A40/3) with hardware release 08.11.

Note:

The fault profile does not cause the on-board electrical system battery to discharge. Generally, the head unit switches back off after 30 min. at the

latest with the ignition key removed.

Cause:

COMAND (A40/3) software error in combination with hardware release 08.11

Remedy:

Update COMAND (A40/3) software. The modified software as of software release 08.28 is available since the Telematics CD Version 11/2008.

Note:

In isolated cases, the complaint may not be rectified after the COMAND software update. The cause my be the switch on the Audio/COMAND

display (A40/8). In this case, replace the Audio/COMAND display (A40/8).

Cause:
The voltage value transmitted by the battery sensor to the rear signal acquisition and actuation module (rear SAM) via the LIN bus is too low,
causing the rear SAM to shut off consumers.
Remedy:
Use diagnosis in the SAM to read out the actual voltage value transmitted by the battery sensor to the rear SAM, and compare it with the voltage
measured directly at the battery using a multimeter.
If a difference> 1V is measurable, the battery sensor must be replaced.

Reason for change
Complaint:
The vehicle does not perform the automatic engine stop although the ECO function was activated via the ECO button.
Cause:
Battery sensor transmitting incorrect temperature value
The temperature value and/or voltage value transmitted by the battery sensor is constant and does not change
Remedy:
IMPORTANT:
- On no account should the sensor be de-energized prior to the test, i.e. do not disconnect the ground terminal on the battery, otherwise a reset
will occur and the result of the function test will be inaccurate.
- Sensors that previously transmitted a constant temperature value could then become OK temporarily, i.e. the fault will not be rectified!
Function test of battery sensor:
a) Check the temperature value:
A battery sensor that transmits a constant temperature value of -40°C or +120°C must be replaced.
A battery sensor that transmits a constant value between -40°C and +120°C must be tested as follows:
- Required aids:
- Xentry
- Multimeter capable of measuring temperatures
1. Measure the ambient temperature at which the vehicle has been kept for some time (e.g. the outside temperature if the vehicle has been
standing outdoors for some time)
2. Measure the outside temperature of the battery on the negative terminal clamp directly at the IBS using a suitable measuring instrument
3. Using Xentry, read out the current battery temperature: - Select BSN - Battery sensor (B95) # Current data of battery sensor # Battery
temperature
- Compare these three temperatures, the ambient temperature, the temperature at the battery negative terminal and the battery temperature (from
Xentry), taking into account a tolerance range of +/- 3°C.
- Repeat the test after approx. 30 mm in order to rule out delayed reaction of the battery sensor to temperature changes.
If the value transmitted by the battery sensor is outside the tolerance, the battery sensor must be replaced.
b) Check the transmitted voltage value:
- Start the engine. Does the voltage value measured by the battery sensor change?
- If the transmitted voltage value remains constant, the battery sensor must be replaced.

Replacement and Diagnosis of FBS3 and FBS4 Components
Troubleshooting in the event of problems with drive authorization or access authorization has been revised:
Procedure:
1. Perform quick test
- Control units
- Body
- EZS
- Special procedures -> "Guided test of transmitter key" or "Guided test of drive authorization system".
2. Select the applicable problem here.
3. In the event of problems with unlocking/locking the vehicle: Carry out a guided test of transmitter key.
4. In the event of problems with starting the engine: Carry out guided test of drive authorization system [DAS]. (A guided diagnosis clearly
determines the defective part.)
These tests check the functional interplay of the electronic ignition lock (EIS), electric steering lock (ELV) and transmitter key:
- "Perform quick test"
- "Check drive authorization system (after quick test)"
- "Check individual parts of the drive authorization system:.......... after Perform quick test"
NOTE:
Do not replace any parts without first performing a guided diagnosis.
Both vehicle keys should be available for an efficient and correct diagnosis. Therefore, ask the customer before their appointment to make
both vehicle keys available on the repair date. If this is not possible, make absolutely certain that you have the correct diagnosis path during
diagnosis with Xentry Diagnostics. Completely carry out the diagnosis up to and including the note referring to the part to be replaced.
Implemented diagnosis steps will be stored in the EZS and ELV control units. When the parts are inspected by warranty claims, the diagnosis
steps taken by the workshop can be identified.
At the end of the respective test steps, a note with the request to prepare a printout appears on the display. This printout and the printout of the
quick test must be uploaded to Paperless SDS.
During the warranty inspection we will check whether the parts have been justifiably removed, based on the diagnosis results. If this is not the
case or if the diagnosis printouts are not uploaded to Paperless SDS, the warranty claim may be denied. The same applies when the requested
parts are not returned. All parts requested by the inspection station are to be returned according to the warranty parts return process.
These parts are explicitly excluded from the Theft-Relevant Parts Ordering Policy.
