My GFs dad A4 Soft top 2006, b6? i think it is, German stuff is new to me unfortunately so I cant really help him.
Basically all the windows dont work at all, no matter what you do, so the drivers side window is stuck part of the way down, which obvioulsy isnt good.
Now we have had a diagnostic machine on it and these fault codes that it brought up
01331 - Door Control Module, Drivers side
00470 - Combination Comfort Databus in single wire
Any help would be greatly appreciated.
