Dotyczy następujących modeli:

Co oznacza ten kod błędu?
The engine control module compares the desired and actual boost pressure from the turbocharger. If the difference becomes too large, the fault is stored, which usually means the turbo is delivering too little pressure. Common causes are air leakage in the intake, a blocked catalytic converter or exhaust system, and a defective turbocharger.
Możliwe przyczyny
- Air leakage in the intake system
- Blocked catalytic converter or exhaust system
- Defective turbocharger
Co możesz zrobić
- 1Check that the hoses to the turbocharger control valve and the hose between the boost pressure sensor and the intake manifold are secure, not leaking and not blocked
- 2Check the intake system for leaks, for example at hose connections and at the air filter housing
- 3If you have a diagnostic tool, activate the turbocharger control valve and listen for a click from the valve
- 4If you have a diagnostic tool, compare the desired and actual boost pressure in live data during a test drive and see whether they follow each other
- 5If the fault remains, have a workshop measure the boost pressure and check the turbocharger and the catalytic converter
Objawy, które możesz zauważyć1
- Poor acceleration, the engine feels sluggish
Na co może wpływać usterka1
- Boost pressure is limited to a basic value
