No sound from radio, no door chime, no audio from blue tooth

2011128i · 06-26-2022, 10:45 AM

Good Morning,
Yesterday my car decided it doesn't want to play music, or give the door chime, or have any audio at all. I have been searching threads looking for help on troubleshooting. I don't want to take it to a dealer. I cant even seem to find any 3rd party service manuals online. Before it quit having audio, there was a lot of electrical interference noise that could be heard through the speakers with volume turned all the way down. Now there is no noise. I am assuming whatever had the interference gave up the ghost. I am looking for where to find service manuals/wiring diagrams, and any tips on what others have experienced.

Thanks

You might want to check for water under the trunk floor in the battery compartment. That's where the amp is located.

My car does this all the time. I turn it off and back on again and everything seems to work fine.

If your amp is dry I'd try
1. turning down the aux input volume
2. seeing if you can straighten out the usb/aux cables running to the ports as they can get bent/kinked
3. replacing the ports

I've had similar issues - distortion and sound occasionally dropping on one side until I crank the volume up. It's not my amp or speakers as I've upgraded everything and the amp is bone dry. The first 2 suggestions have helped for me and I'm about to replace my 6FL port as well.
