Turbocharger, Removing And Installing [XXXX]: Notes
If mechanical damage (such as a destroyed compression wheel) is found on the turbocharger, just replacing the turbocharger is not enough. To avoid damage later, perform the following steps:
- Check the air filter housing, air filter element and air guide 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.
Special tools and workshop equipment required
- Hose Clip Pliers:VAS6362
- Socket Bit XZN 10:T10501
During installation, install all heat insulation sleeves at the same locations.
