Removal And Installation: Turbocharger: 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.
