I opened my trunk on my B8 a4 2008 sedan and noticed water coming from my left tail light (the part that lifts up with the trunk) I didn't think much of it at first, but grabbed a towel and cleaned it up. When I started the car no sound was coming from my speakers, no radio, no gps sound, no cd sound nothing. If i go to the "sound" setting on the mmi display the mmi freezes and i have to reset it.
I looked at the amp (in the trunk, left side) and sure enough it had a couple of water droplets on it.

what can i do here?
