Turbocharger, Removing And Installing: Installing
If mechanical damage (such as a destroyed compression wheel) is found on the turbocharger, just replacing the turbocharger is not enough. To avoid subsequent damage later, perform the following steps:
Check the air filter housing, air filter element and air duct hoses for contamination.
Check the entire charge air circuit and charge air cooler for foreign objects.
If there are foreign objects in the charge air system, clean the charge air circuit and replace the charge air cooler if necessary.
Install In Reverse Order Of Removal. Note The Following:
- Hose connections and charge air system hoses must be free of oil and grease before installing. On connector couplings, the seal and sealing surfaces must only be lightly oiled.
- Install only approved clamps for securing hose connections.
- Replace gaskets, seals and self-locking nuts.
- Replace the turbocharger clamp and catalytic converter after removing.
- Fill the turbocharger with engine oil at the connection for oil supply line.
- After installing the turbocharger, let the engine run at idle for approximately one minute and without increasing the engine speed. This ensures the turbocharger is supplied with oil.
After Reinstalling The Turbocharger
-- Pry out the seal -1- from the turbocharger -2-. Insert the screwdriver -3- in the opening -arrow-.
Turbocharger with Mahle Charge Air Pressure Actuator -V465-
-- This Charge Air Pressure Actuator -V465- has a protective boot.
Check the boot for damage before installing and replace if necessary.
After installing, check the boot for correct seating.
The Charge Air Pressure Actuator -V465- function must not be impaired.
-- Place the boot -1- as shown around the Charge Air Pressure Actuator -V465- -2-. Close the snap fasteners -arrows-.
-- After installing new parts (engine/partial engine, cylinder head or turbocharger) limit the oil pressure regulation for approximately 1000 km to the higher pressure stage. From this, the higher friction is taken into account when breaking in new components, and the optimum removal of particles from the initial wear in is ensured. To do this connect the vehicle diagnostic tester, switch on the ignition and select the following menu items:
- 01 - Engine Electronics
- Guided Functions
- 01 - Oil Pressure Regulation/Retraction Activating
