Having thought I was sorted when VW quoted around ?200 to fix my window and another small problem as per my earlier post I finally got the car back today.
End result was a bill for ?400, they replaced the regulator but then reported that because the motor had been working against a partially and then a fully seized mech the motor had burnt out. It would power the window up and down but very slowly. The cost of a motor ?159+VAT. Could be your motors have suffered the same?
The window now works like a dream, but handing over ?400 hurt, a lot!
