Co oznacza ten kod błędu?
The actuator for turbo bypass valve A has stuck in the closed position. The fault is mechanical and shows when the engine control module expects the valve to open but it does not.
Możliwe przyczyny
- Mechanical fault where the actuator for bypass valve A is stuck in the closed position
- The valve is binding in its position and cannot move to open
Co możesz zrobić
- 1Check that the fuses for the turbo control are intact. Their locations are given in the instruction manual
- 2With a diagnostic tool, activate bypass valve A and listen for the actuator to move. No movement suggests it is stuck
- 3Inspect the linkage to the valve for damage, wear and dirt
- 4Have a workshop with diagnostic equipment check the actuator and the control signals to the valve
- 5Repair what is found, clear the code and road test the car to see whether it returns
Objawy, które możesz zauważyć2
- Noise while driving, especially just after the accelerator pedal is released
- The noise may be heard at some times or all the time, which cannot be predicted
