It seems that the electronic braking system in my 04 E320 has begun to interfere with the AM radio. When I apply the brakes when the car is in motion, the AM radio becomes all static. When I either release the pedal, or the car comes to a full stop, then the reception goes back to normal. Mind you, this only happens when the car is moving, so it's obviously caused by the brakes actually working, and not by the lights or anything else. Wierd.
Anyone else ever hear of this?
