Was bedeutet der Fehlercode?
The engine control module (ECM) compares the measured boost pressure with its target value. If the boost pressure becomes lower than the target, a fault is registered. The cause may lie in the valve, the hoses or the charge air cooler, or in the wastegate valve and its pressure servo.
Mögliche Ursachen
- Damaged turbocharger control valve
- Damaged charge air cooler
- One hose from the wastegate valve servo to the turbo control valve has worked loose, or is clogged or cracked
- Hoses between the turbocharger control valve and the charge air pipe are blocked or damaged
- Incorrectly adjusted or damaged pressure servo on the wastegate valve
- Sticking wastegate valve
Was Sie tun können
- 1Check that the hose between the wastegate valve pressure servo and the turbocharger control valve is correctly fitted and not damaged or blocked
- 2Check that the hose running from the charge air pipe to the turbo control valve is fitted correctly and is neither damaged nor clogged
- 3Check that the charge air cooler is not blocked
- 4With a diagnostic tool: activate the turbocharger control valve and check that it clicks. A damaged valve can be hard to detect that way
- 5Check that the wastegate valve moves freely and is not sticking. Setting the pressure servo is a job for a workshop
