Gearbox oil
The 7-speed dual clutch gearbox has two separate and different
oil systems. One for the gearbox oil section -arrow A- and one for
the hydraulic fluid section -arrow B-.
Only the gearbox oils available through the replacement parts
system must be used for the dual clutch gearbox 0CG. Other oils
will lead to malfunctions or failure of the gearbox, part number ⇒
Electronic parts catalogue “ETKA” .
Do not mix »additives« in oil.
Oil which has been drained out cannot be added again.
The oil level in the gearbox cannot be checked. The oil level can
only be adjusted by changing the gearbox oil, e.g. in the event of
leaks on the gearbox
⇒ “6.1 Draining and filling gearbox oil”, page 86
