Removing
Caution
If the turbocharger has suffered mechanical damage (e.g.
damaged compressor wheel), it is not sufficient merely to fit a
new turbocharger. The following work must be performed in
order to avoid further damage:
♦ Check air cleaner housing, air filter element and air hoses
for dirt and foreign particles.
♦ Check the entire charge air system (including the charge
air cooler) for foreign matter.
♦ If foreign matter is found in the charge air system, clean
all relevant ducts and hoses and renew charge air cooler
if necessary.
Note
Rules for cleanliness

All cable ties which are released or cut open when removing
