3.1 Rules of cleanliness
♦ Thoroughly clean the connection points and their surround‐
ings before disconnecting.
♦ Seal the open lines and connections immediately with a
clean plug, e.g. from the plug set such as -VAS 6122-.
♦ Only install clean parts: remove spare parts from their wrap‐
ping immediately before fitting.
♦ Make sure no dirt gets into the gearbox when the gearbox is
open.
♦ Always replace paper gaskets after disassembly. Completely
remove old gaskets and thoroughly clean sealing surfaces.
♦ Place removed parts on a clean surface and cover them to
prevent them from getting dirty. Use sheeting and paper for
this purpose. Use lint-free cloths!
♦ Carefully cover or close opened components if the repair is
not completed immediately.
♦ Protect electrical plug connections from dirt and moisture
and only connect them when dry.
3.2 General points
Gearbox
♦ The engine torque is transferred onto the double clutch via
the flywheel. The flywheel and the double clutch are inter‐
connected via a serration. Both together have the function of
the two-mass flywheel.
♦ The gearbox is built like a 7-speed manual gearbox. Due
to the alternative hydraulic activation of the two multi-plate
dry clutches, it is operated like an automatic gearbox. This
means that the gears are automatically or manually engaged
via the Tiptronic mode. A clutch pedal is not present.
♦ Both clutches are open when the ignition is switched off.
Part transmission 1 engages the 1st gear and part transmis‐
sion 2 engages the reverse gear.
Gear oil
The “7-speed double clutch gearbox DSG - 0CW” has two
separate, different oil fillings. One for the area with gearbox
oil -arrow A- and the other one for the area with hydraulic oil
-arrow B-.
