Torque wrench (5…50 Nm) -V.A.G 1331-
Caution
When a mechanical fault is found on the turbocharger, e.g.
a destroyed compressor impeller, it is not only sufficient to
renew the turbocharger. To prevent this from causing fur-
ther damage, perform the following repairs:
◆
Check air filter housing, air filter element and intake ho-
ses for soiling.
◆
Check complete charge air system and, if fitted, charge
air cooler for foreign objects.
If foreign objects are found in the charge air system, the
charged air routing must be cleaned and the charge air
cooler must be renewed, if necessary.
