Volkswagen Golf Variant, Jetta. Manual — part 14
The clutch is self-adjusting. Shocks can have an effect on this
adjusting device. Even if the mechatronic unit has been re‐
moved, the “sudden removal” of the assembly lever -T10407-
from under the engaging levers can have a negative effect on
the adjusting mechanism.
♦
In order to remove the mechatronic unit, sufficient space must
be available in front of the gearbox. In some vehicles, parts
must be removed which do not have anything to do directly
with the gearbox. Remove any charge air lines or coolant lines
that may be present.
♦
Any retainers fitted on the cover of the mechatronic unit must
also be removed.
♦
A “new” mechatronic unit is correctly filled with oil.
♦
Do not drain oil. A “removed” mechatronic unit is sent back
with its oil in.
Mechatronic unit remains filled with oil.

ers of mechatronic unit. Otherwise, levers will jam mechatronic
unit at plungers and prevent mechatronic unit from being re‐
moved.

Both levers must now be carefully pressed away from the plung‐
ers.
