1.3.2 Hose connections with spring band ring
Note
There is a danger of a „hose detaching" whilst driving after re‐
moving and reinstalling charge pressure lines with spring-type
clips. For this reason, spring band rings are used which can be
opened if a defect item requires the charge pressure line has to
be disconnected. In cases of repair, the charge air pipe must be
removed if necessary, the spring band ring must be destroyed
using a suitable tool (e.g. angled grinder) and must be renewed
by a replacement part according to ⇒ ETKA (electronic parts
catalogue) .
1.4 Assembly overview - turbocharger with
attachments
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 further damage,
perform the following repairs:
♦ Check air filter housing, air filter element and intake hoses
for soiling.
♦ Check complete charged air routing and charge air cooler
for foreign objects.
If foreign objects are found in the charge air system, the charg‐
ed air routing must be cleaned and the charge air cooler must
be renewed, if necessary.
