Here is a new one for me.

Started the 540 this weekend to be greeted by my radio playing highly distorted audio at a very amplified volume. Initially, my thought was maybe the BlueBus module failed, so I switched it to FM, but with no change.

I needed to shut down and restart the entire car to fix the issue, and all was back to normal.

It's happened a couple more times since the initial symptom, and is seemingly random, and not every startup.

It is getting warmer here, maybe that is causing something to go wild in the head unit?

Has anyone ever experienced this on their E39?

It's an OEM MID head unit, used primarily via BlueBus, which has been installed since the winter with no issues.

Probably the amp in the trunk is telling you it's ready to go.

Either the amp is on the way out, or something is telling it to play at max volume.
