| Effects of leaks in charge air system |
| A - Leaks downstream of air mass meter |
| t
| Possible causes of trouble: |
| 1 - | Connecting hose between air mass meter -G70- and turbocharger |
| 2 - | Connecting hose to crankcase breather |
| 3 - | Connecting hose to activated charcoal filter |
| B - Leaks downstream of turbocharger (intake side) |
| t
| Possible causes of trouble: |
| 1 - | Connecting hoses and pipes between turbocharger and charge air coolers |
| 2 - | Hose between charge air coolers and intake manifold |
| 4 - | Seal of charge pressure sender -G31- (in air intake pipe) |
| 5 - | Gasket between throttle valve module -J338- and intake manifold |
| 6 - | Gasket between intake manifold and cylinder head |
| 7 - | Connecting hose to solenoid valve for charge pressure control -N75- |
| - | Inadequate charge pressure |
| C - Leaks downstream of turbocharger (exhaust side) |
| t
| Possible causes of trouble: |
| 1 - | Connection between turbocharger and exhaust manifold |
| 2 - | Connection between exhaust manifold and cylinder head |
| - | Inadequate charge pressure; possible smell of exhaust gas, traces of soot in engine compartment |
