I have a 2015 Passat sport with radio issues. When I bought the car I had the dealer install a factory remote starter. The blue tooth stopped working after that so they took about a month to replace the bluetooth module, remote starter and radio. Finally an enginer from VW figured out the issue. Fast foward 13 months and the radio turns off and on on its own. I pulled the radio and noticed the radio had a remanufactured sticker on it. I checked the fuse on the back of the radio and it appears fine. Any suggestions to what is causing this issue? Kinda pissed the dealer installed a used radio. Any help is greatly appreciated.
