HELP! Speakers on passenger side not working !
 

New owner of a 2008 A5 3.2 w/ B&O and noticed that the entire passenger side of speakers aren't producing any noise whatsoever. Fader/balance nor the volume make any difference on either nav, radio, or aux. I just had it serviced at the dealership for the door handle on the passenger side if that may be the culprit. Also checked the amp area in the trunk for anything and everything looks normal no water stains on the foam or any signs of water or rust anywhere. Any help is greatly appreciated, thank you !

Find a video on how to take off the inside door panel and just check that they plugged the wiring harness in all the way. I took my door panel off to service my latch once and when I was done I had the same problem. took off the door panel and the plug I was sure I had put back in was loose. plugged it in and no problems. worth a check!
but make sure you watch a video, as if you just start yanking the wrong directions or too hard or forget a hidden screw, the little pins will break and if too many of them do your door panel will rattle and drive you nuts.
