Hi All just thought id share if it already hasn't been i lost power to my front doors no windows worked wing mirror stopped and central locking to drivers door, so after stripping own the dash under the wheel to get to the fuse box to check all wires and taking the door cards of and looking couldn't find any damaged wires it turns out that it was the ground wire to the module in the door that had dis connected somewhere in the rum so ive snipped it and joined a new wire to a bolt that has a ground in the door all working again now . just thought i would share in case someone else has this problem

Diane. Have you read the whole thread? There are suggestions near its start, and questions which would help all of us to home in on your problem.

Hi, I had the same problem on my 2017 a4 allroad last year, same place, o/s/r lower, I had mine replaced at an independent v w garage at just over £100. p.s. my brother, who has the identical car had his go as well on the o/s/r/ seems funny it is always the o/s/r. that goes.

And no vibration at the steering wheel or pedals? In that case I would look to the rear tyres being damaged or out of balance as the most likely candidate. That does not rule out other possibilities such as worn wheel bearings, loose wheel nuts, warped brake discs but they wou;d cause symptoms that you have not mentioned.
