Verification




Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on
- Start the engine.
Check the camshaft adaptation by reading off the adaptation values of the camshaft (flanks 1-4). All values must be between -7° and +7°.
Turbocharged engines:When checking, the accelerator pedal (AP) must be depressed slightly but the engine speed must be below 1200 rpm.
Naturally aspirated engines:When checking the engine must be idling.

Hint: Theoretically the values for flanks 1-4 should be the same, however because of mechanical tolerances the values may vary between the different flanks by approximately ±2°.





Are all the adaptation values correct?

Yes - Verification completed

No - Fault-tracing information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing

No - Attempt New Test
