This description only applies to installed gearboxes. If gearbox

has been removed, first remove clutch then mechatronic unit.
♦ Move mechatronic unit for dual clutch gearbox -J743- into “re‐

moval position” by hand 

⇒ page 62

 .

Special tools and workshop equipment required
♦ Assembly lever -T10407-

♦ Drip tray for workshop hoist -VAS 6208-

♦ Vehicle diagnostic tester
Perform the following steps:
In order to remove the mechatronic unit, sufficient space must be

available in front of the gearbox. Depending on the vehicle, parts

must be removed which do not have anything to do directly with

the gearbox. For example, the air filter housing and, if present,

charge air lines or coolant lines.
Any retainers fitted on the cover of the mechatronic unit must also

be removed.
The vehicle diagnostic tester brings the mechatronic unit into the

correct position for removal. All gear actuators are moved “into

neutral”.
In this position, insert assembly lever -T10407- between release

lever and gearbox housing. This makes it possible to remove load

from plungers of mechatronic unit so that they may be removed

by hand from cups of engaging levers.
Mechatronic unit can be removed and inserted. When installing,

make sure clutch plungers are correctly seated in cups of engag‐

ing levers.
Therefore, please follow description below step by step.
