Just bought a new '97 BMW M3.
I notice a buzzing from behind the radio;A/C;computer that lasts for about 15 minutes following turning the car off, and then it goes away. It sounds almost like a small fan or maybe transformer and I can't fully pinpoint quite where it's coming from in there. I find it strange that it lasts for exactly 15 minutes and then goes away after the car is turned off. It seems to happen in accessory mode as well.
Is this any known problem or should I start disassembling?
