Checking charge air system with turbocharger
Effects of leaks in intake or exhaust system
A - Leaks downstream of air mass meter
- 1 - Connection hoses between air mass meter and exhaust turbocharger
- 2 - Connection hose to crankcase vent
B - Leaks downstream of exhaust turbocharger (intake side)
- 1 - Connection hoses between turbocharger, charge air cooler, and intake pipe
- 2 - Intercooler
- 3 - Seal underneath intake manifold pressure sender -G71/intake manifold temperature sender -G72
- 4 - Seal between intake connection and intake manifold
- 5 - Seal between intake manifold and cylinder head
C - Leaks downstream of exhaust turbocharger (exhaust side)
- 1 - Components of exhaust gas recirculation
- 2 - Turbocharger/exhaust manifold connection between (engine code AGR only)
- 3 - Connection between exhaust manifold and cylinder head
- - Boost pressure too low, possibly exhaust odours, traces of soot in engine compartment
