Constant beeping & Radio stay on
Just happened today. 2007 E60 525xi w/ iDrive, GPS, parking sensors.
I started the car, put it in reverse (the parking sensors went on, and the beeping started). I backed up, put the car in Drive (yeah its an automatic) and the beeping continued as though it was sensing another vehicle/object close to the sensors. The sensors were clean. I turned the sensors off, and the beeping continued. Then the radio was silenced. It continued beeping while I was in the service station filling the tank. When I got back in, and drove off, the radio came on, along with the beeping. When I got home, I turned the engine off and removed the key. The beeping and the radio continued to stay on. I pulled the manual to see about pulling fuses, and just as I was opening the fuse box cover, the radio and the beeping quit. During this episode the OBC lists all system OK.
Anyone have any ideas? I am just happy that the beeping stopped and not have the battery drain.
