General instructions for charge air system
  WARNING
When undertaking all installation work, particularly in the engine compartment because of its cramped construction, please observe the following:
t  Lay lines of all kinds (e.g. for fuel, hydraulic fluid, cooling fluid and refrigerant, brake fluid, vacuum) and electrical lines in such a way that the original line guide is re-established.
t  Ensure that there is adequate free access to all moving or hot components.
  Caution
In case a mechanical damage to the exhaust gas turbocharger is found, e.g. damage to the compressor wheel, it is not sufficient to only replace the turbocharger. In order to avoid consequential damage, perform the following tasks:
t  Clean all oil lines.
t  Change engine oil and oil filter.
t  Check air filter housing, air filter element and charge air pipes as well as charge air hoses for soiling.
t  Check all the air guides and the charge air cooler for foreign bodies.
If foreign bodies are detected in the charge air system, the complete charge-air routing must be cleaned and if necessary the charge air cooler must also be replaced.
t  The charge-air system must be tight, check → Chapter.
t  Replace the gaskets, the sealing rings and the self-locking nuts.
t  Hose connections and hoses of the charge air system must be free of oil and grease before being installed. Only gaskets and sealing surfaces of the push-fit couplings are coated with oil → Chapter.
t  Observe assembly markings on the hoses and components.
t  All hose connections of the charge air system are secured with spring strap clamps or push-fit couplings.
t  Only install approved clamps for securing the hose connections → Electronic Catalogue of Original Parts.
t  Use pliers for spring strap clamps to fit the spring strap clips.
t  Assembly of hose connections with push-fit couplings → Chapter.
t  Before screwing down the oil feed line, fill the exhaust turbocharger via the connection fitting with engine oil.
t  After installing the turbocharger, run engine at idling speed for about 1 minute to ensure that oil is supplied to the turbocharger.
