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.

– Unscrew bolts of mechatronic unit for dual clutch gearbox -

J743- “in diagonal sequence”.

“There are 4 long and 3 short bolts.”
Do not remove more than 7 bolts!
– Please look carefully to check which bolts you are unscrewing.

Do not unscrew any cover bolts.

The gearbox is shown here again from the side to make this sit‐

uation clearer.
The mechatronic unit must be removed. The cover does not have

to be removed.
Therefore, do not remove more than 7 bolts!

The next step is “difficult”:
Now press both engaging levers of dual clutch “away” from plung‐

ers of mechatronic unit. Otherwise, levers will jam mechatronic

unit at plungers and prevent mechatronic unit from being re‐

moved.
– Please read through this description all the way to the end first.

This will help you to perform the following steps “correctly”.

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

ers.
– First take a look at -reddish-brown- engaging lever in this pic‐

ture.
