Maintenance Manual
If necessary, remove the Bowden cable (11) for wastegate
control. See 78-00-00 sec. 3.6. This is normally not necessary.
There is no need to disassemble the complete unit of muffler -
turbocharger - exhaust manifold for the removal of the muffler
bracket.
These screws cannot be removed completely straight away as
they touch the bearing housing. For complete removal, it is
necessary to slacken the fourth attachment screw slightly.
To prevent any damage to the turbine impeller, fit the attachment
screws (20) again. This will ensure that the turbine housing will not
separate from the impeller.
Ensure that the two retaining ring halves are in position.
