  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.

Installation is performed in a similar way in the reverse order. Pay attention to the following points:
  Note
t  Replace the gaskets, the sealing rings and the self-locking nuts.
t  Fill exhaust turbocharger with engine oil through the connection fitting of the oil feed line.
t  Hose connections and hoses of the charge air system must be free of oil and grease before being installed.
t  Secure all hose connections with corresponding hose clips.
–  Observe the assembly instruction for hose connections with push-fit couplings → Chapter.
–  Checking the oil level → Octavia II.
  Note
after installing the exhaust turbocharger run the engine approx. 1 minute in idle and do not increase speed immediately in order to ensure the supply of oil to the turbocharger.
