Was bedeutet der Fehlercode?
The turbocharger (TC) control valve regulates boost together with the wastegate valve, and the code indicates that boost is too high. The fault may be permanent, meaning it is present now, or intermittent, meaning it only appears from time to time. The causes lie in hoses, in valves and in the wastegate valve's pressure servo.
Mögliche Ursachen
- Hoses between the turbocharger and the turbocharger (TC) control valve have come loose or are blocked or damaged
- Hoses between the turbocharger (TC) control valve and the pressure servo have come loose or are blocked or damaged
- Faulty turbocharger (TC) control valve
- Faulty pressure servo for the wastegate valve
- Sticking wastegate valve
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it returns
- 2Check that the hoses between the turbocharger, the turbocharger (TC) control valve and the pressure servo are not pinched, blocked or damaged
- 3With a diagnostic tool, activate the turbocharger (TC) control valve and listen for a click
- 4Check that the wastegate valve's pressure servo works and that the wastegate valve does not stick
- 5If the hoses and valves are intact but the fault remains, have a workshop check the setting of the wastegate valve
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
- Boost pressure may be lower than normal
