Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the adaptation of the compressor bypass valve, meaning the learned values that control it. The code is stored when an adaptation value falls outside a predefined range.
Mögliche Ursachen
- The bypass valve adaptation value is outside the expected range
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connections to the bypass valve are fully seated and free from corrosion
- 3Look for dirt or sticking at the compressor throttle and clean it if necessary
- 4Have a workshop reset the bypass valve adaptation once the mechanical parts have been checked, then confirm with a road test that the code does not return
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
