2013 VW CC - Rear whine - Klg
Has anybody had any success with VW over a fault with the design of the rear suspension of the Passat range that causes "cupping " to the tread on the inside of the rear tyres creating a whine similar to a faulty wheel bearing .
Attempts to get the fault recognised under warranty have so failed , stating that tyres are not covered under warranty

The problem with the tyres has been caused by the geometry of the car.

You need to get a 4 wheel allignment, then new rear tyres.

Whether you can get VW to contribute to the cost will be another matter.
