On a small number of vehicles, the gearbox may not be filled to the correct oil level. As a result, the clutch could slip and cause a loss of power to the wheels. Additionally, when driving the vehicle on a racetrack, oil could leak through the breather valve.
A loss of power to the wheels could increase the risk of a crash. Oil that leaks onto hot engine parts could cause a fire.
Audi will notify owners by mail and instruct you to take your vehicle to a dealership to inspect and correct the oil level in the gearbox, as necessary.
