The Audi 01J, or Multitronic VL-300, continuously variable transmission was produced by the German company from 1999 to 2013 and installed on front-wheel drive versions of popular models such as the A4 B6, A6 C5, and A8 D3. This CVT was designed for engines with up to 310 Nm of torque.

In 1999, engineers at the German company LuK developed a new CVT for Audi, featuring a pull chain and clutch pack instead of a torque converter. This transmission was installed on front-wheel-drive models with a longitudinal engine layout and torque of up to 310 Nm. An updated version in 2004 was equipped with a 330 Nm engine. Also in 2004, a reinforced 0AN modification for diesel engines with torque of up to 380 Nm was released.

Using
The transmission was installed on:
- Audi A4 B6 (8E) in 2000 – 2004;
- Audi A4 B7 (8E) in 2004 – 2008;
- Audi A6 C5 (4B) in 1999 – 2005;
- Audi A6 C6 (4F) in 2005 – 2011;
- Audi A8 D3 (4E) in 2003 – 2010;
- Seat Exeo 1 (3R) in 2008 – 2013.
Disadvantages of the VW VL300 gearbox
- The most common reason for service calls is transmission slippage caused by a stretched chain. Its lifespan depends on driving style, and active owners replace the chain as early as 100,000 km.
- Frequent and abrupt starts also wear out the friction clutches, which act as a clutch. This dirt then gets into the oil, clogs the solenoids, and the transmission begins to struggle.
- The second most common problem is replacing the electronic transmission control unit, which is located inside the transmission and does not tolerate hot oil. So clean the radiators.
- Also, forums complain of a loud hum due to worn driven cone bearings. If this is not detected in time, it will damage the bearing seat, making repairs more expensive.
- Weak points of such CVTs include short-lived cooling pipes, the ejector pump, the torque sensor, the planetary gear, and the differential. Towing with the engine off also results in scoring on the cones.
