Possible cause:
- Y49/7 (Right camshaft exhaust solenoid)
Affected functions:
- Engine diagnosis
- Engine output
-------------------------------------------------
Test 1: Check component Y49/7 (Right camshaft exhaust solenoid).
1. Check component Y49/7 (Right camshaft exhaust solenoid).
Test 1.1: Test actuation of component Y49/7 (Right camshaft exhaust solenoid).
Test 1.2: Test current consumption of component Y49/7 (Right camshaft exhaust solenoid).
1.1. Test actuation of component Y49/7 (Right camshaft exhaust solenoid).
Test prerequisite
- Engine at idle
- Vehicle stationary
- Coolant temperature > 80锟斤拷 C
- Time since engine start> 60 s
Status of relevant actual value:
- Temperature of coolant:Warning! Communication with ECU required.
Note
- After the actuation it may be necessary to erase the fault memory!
Proceed to 'Actuation' with F2
