Ok, so I have been dealing with this problem in the driver's side rear window for a few weeks but yesterday the passenger side rear window did the same thing and I cant find any information on this AT ALL!
Heres what happened:
As I was rolling down the window I heard a snap and the window fell to the fully down position and now it wont go back up on its own. It rolls down just fine but when i try to roll it up I hear the motor turning followed a few seconds later by a thud but the window goes no where. Im really confused bacause I called Audi and they told me it was the regulator (they want 500 a side to fix). I would think it would be more like a simple plastic piece sanpping or somehting along those lines.

Your healp would be GREATLY appreciated! I would rather not spend 1000 bucks to find out that its not the porblem.
Thanks guys,
Dave

 

Sounds like the wire that reels the window up and down snapped, usually when a window regulator goes out. It makes a crunching noise and kinda goes crazy. When I did my drivers door, I noticed that the plastic wheel was eating up the wire which leads me to the wire snapping theory. Unfortunately the window regulator comes in 1 piece w/everything you need. Although it could of just feel out of the rails. Best thing to do is to take the door panel off and get a better look.

 

Thank you for the input. Ill take the panel off when I get the chance.

 

I just had the same problem last night. I was driving and I put the rear driver side window down and I heard a loud crack and now the window won't go up and easily falls down. Does anyone know how to fix it or who I should take it to to fix it and how much the repairs will cost?

 

How does one take the panel off as well with breaking anything else?

 

if you go to A4 Mods.com under "stereo and interior" there is a tutorial on peeling window switches that explains how to remove the door panel.

 

Does anyone know how to remove the rear door panel, it seems to be a completely different beast than the front door panel.

 

this happened to me twice while the car was still under warranty. the dealership said both times that it was the regulator. had the same symptoms as described here

 

Yeah that is great, can somebody tell me how to take the rear door panel off?
