Oil circuit – hydraulic system
Oil circuit
The double-clutch gearbox operates with two independent oil circuits using two different oils:
- Oil circuit for mechanical gearbox
- Oil circuit for mechatronic module
Each oil circuit contains an oil which is specifically suitable for to its requirements.

Oil circuit - mechanical gearbox
Oil circuit - mechatronic module
The oil supply to the shafts and gears of the
mechanical gearbox is carried out in the same way as
for a normal manual gearbox. It will not therefore be
dealt with in any greater detail here.
The oil supply for the mechatronic unit is separate
from the oil circuit for the mechanical gearbox.
An oil pump delivers the oil at the pressure required
to enable the hydraulic mechatronic unit components
to function.
The oil volume in the mechanical gearbox is 1.7 l.
The oil volume in the mechatronic unit is 1.1 l.
For the precise capacities, please refer to the current Workshop Manual,
"The 7-speed Double-clutch Gearbox 0AM".
