Special tools and workshop equipment required
t  Pliers for spring strap clamps
  Caution
In case of mechanical damage to the exhaust gas turbocharger, e.g. damage of the compressor wheel, it is not sufficient to only replace the exhaust gas turbocharger. In order to prevent consequential damage to the engine, perform the following tasks:
t  Check air filter, air filter insert and charge air hoses as well as charge air pipes for soiling.
t  Check all the air guides and the charge air cooler for foreign bodies.
If soiling or foreign bodies are detected in the filling system, all air guides must be carefully cleaned and if necessary replace the charge air cooler.
