Effects of leaks in charge air system |
A - Leaks downstream of air mass meter |
Possible causes of trouble: |
1 - | Hose connecting air mass meter to turbocharger |
2 - | Connecting hose to crankcase breather |
3 - | Connecting hose to mechanical turbocharger air recirculation valve |
B - Leaks downstream of turbocharger (intake side) |
Possible causes of trouble: |
1 - | Air intake hoses and pipes between turbocharger and charge air cooler |
2 - | Air intake hoses and pipes between charge air cooler and intake manifold |
4 - | Seal underneath charge pressure sender -G31- |
5 - | Seal between throttle valve module and intake manifold |
6 - | Gasket between intake manifold and cylinder head |
- | Inadequate charge pressure |
C - Leaks downstream of turbocharger (exhaust side) |
Possible causes of trouble: |
1 - | Connection between exhaust manifold and turbocharger |
2 - | Connection between exhaust manifold and cylinder head |
- | Inadequate charge pressure; possible smell of exhaust gas, traces of soot in engine compartment |
