My 05 X5. So here's a new one. Yesterday, turned the car on, radio was off and got unbelievable static from the left rear door speaker. Turned the radio on and off, nothing helped. As it was late in the aft. I called BMW and they never heard of such a problem but couldn't take it in.Drove some more and then the right front started. Was all set to go to the dealer this morning, and guess what no noise last night after the care sat for about an hour. Had lots of rain yesterday, could it be a short. Anyone else ever have this?
