What does this fault code mean?

The engine control module compares the exhaust camshaft position with the crankshaft position and adjusts the adaptation when they do not agree. The code concerns sensor B, bank 1, and is set when the adaptation value rises above a limit. Adaptation is carried out during engine braking, and the code is checked once it has been completed.

Possible causes

Incorrectly set camshafts
Damaged VVT unit

What you can do

1Read the code and note whether it is active right now or only stored
2If you have a diagnostic tool: read the exhaust camshaft adaptation in live data with the engine running and note the value
3Check that the engine oil level is correct and that the oil is clean and of the right quality
4Have a workshop check the exhaust camshaft basic setting
5Have a workshop clean the control valve, or try a new one if the fault remains
6If the fault returns: have a workshop check the VVT unit

Symptoms you may notice5

The car lacks power, especially when pulling away from standstill
Engine does not start, the starter motor cranks it
Engine is hard to start and cranks slowly
Uneven idle
Engine hesitates or runs jerkily on acceleration

What the fault can affect1

The control module uses a fixed value for the camshaft adaptation

General guidance for car owners. Diagnosis on the car can point to a different cause.
