Audi's 0AW gearbox is currently considered the most resistant cvt. The common failure phenomenon is mainly concentrated in the vehicle start, driving noise and shaking, compared to other steel belt cvt, almost no chain breakage occurs.
The most performance is the start slippage fault, usually because the clutch problem, but also most of the vehicle's common problems.
Clutch inspection should not only look at the most intuitive piece whether slipping or burnt, but also need to check the sealing of the piston, because the iron piston is easy to leak pressure, single replacement of the plate is only a symptomatic treatment. Replacement of friction plate and piston can solve the problem if the symptoms are mild, and it is recommended to directly replace the clutch if it is burned seriously.
For the problem of resonance accompanied by starting noise, the main check damping disk, which is usually about 1 centimeter left and right rotation, and rotation to the end of the trip will have a sense of damping, both are indispensable.
Vehicle driving noise is serious, excluding tire bearing damage, you need to focus on checking the pressure cylinder bearings on the transmission case, where the inner wall of the bearings are prone to damage pitting.
Another common problem is the left half shaft positioning bearings outside the shell wear caused by bearings and shells between the gap, this problem is manifested in the vehicle driving or turning when the vibration is large, similar to the knocking of the loud noise, the current effective repair method is to add the excessive gap in the iron set to solve the problem.
The above briefly summarizes the common problems and treatments for this transmission.
