Good day all, As above, I have just replaced the window regulator on my drivers side, connected everything back up, all screws in place and everything was fine. However, now my radio will switch on, play for about a second then fade out and only slight distortion noise is heard. Radio has been taken out and put in my other car, which works fine but as soon as its put back in the A3, nothing. Can anyone provide some advice? thanks in advance. Car is a 2004/5 A3 1.6FSI if thats of any use.
