Volume: 1 Liter (factory-sealed bottle).
This specific fluid contains a 4% friction modifier additive.
This premium fluid is specifically formulated to lubricate and protect Audi's quattro drivetrain systems.
Torsen-type Center Differentials / Transfer Cases: It is heavily used in the center transferbox attached to ZF 6-speed (6HP) and 8-speed (8HP) automatic transmissions.
The 4% friction modifier is highly critical here because it prevents internal clutch plate "chatter" or shuddering during tight turns while preserving the differential's lock-up capabilities. Front and Rear Differentials: Depending on the specific drivetrain configuration of the vehicle, it is also used as a premium front or rear axle oil.
It is used across a vast array of Audi models equipped with permanent quattro all-wheel drive, including:
Sedans / Coupes / Wagons: Audi A4, S4, A5, S5, A6, S6, A7, S7, A8, S8
SUVs: Audi Q5, SQ5, Q7, RSQ8
