3. Power supply
Voltage supply via component Z7/38 (Circuit 87 M1i connector sleeve)
Possible cause and remedy
- Check voltage supply according to wiring diagram.
4. Check component Y49/4 (Left camshaft intake solenoid).
Test 4.1: Test actuation of component Y49/4 (Left camshaft intake solenoid).
Test 4.2: Test current consumption of component Y49/4 (Left camshaft intake solenoid).
4.1. Test actuation of component Y49/4 (Left camshaft intake 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
4.2. Test current consumption of component Y49/4 (Left camshaft intake solenoid).
