- Unscrew bolts (3).
- Only loosen bolts (2).
- Remove bolt (1).
- Unscrew studs (1 … 8) using bit XZN 10T10385.
- Carefully remove turbocharger (9).
- Observe tightening sequence for turbocharger .
- Renew seals, gaskets, O-rings and self-locking nuts after removal.
- Fill turbocharger with engine oil at connection for oil supply line.
- Hose unions and air intake pipes and hoses must be free of oil and grease before installation.
- Secure all hose connections with the hose clips corresponding to original equipment Electronic Parts Catalogue.
- After installing turbocharger, run engine for about 1 minute at idling speed to ensure that oil is supplied to turbocharger. [Note: After new components have been installed (engine/short engine, cylinder head, camshaft housing or turbocharger) the oil pressure control must be set to max. pressure for approx. 1000 km if the function is available in the engine control unit. This will compensate for the increased friction during run-in of new components, and a better transport of wear-related particles is guaranteed.]
- Connect .
- Switch ignition on.
- Activate oil pressure regulation , 01 - Systems capable of self-diagnosis, 01 - Diesel direction injection and preglow system EDC 17, 01 - Engine electronics functions, Adaption, Oil pressure for engine operation.
- Follow further instructions displayed on .

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
