2003 w211 320 avantgared I was backing the car into a tight area,
(to unload shopping) the weather was awful.At night, raining heavily,
so visibility very poor.The next thing BUMP. No audible warning, must
admit I didnt notice the warning lights as was too busy trying to check
rear view mirrors & at 75 with glasses, Not easy. Luckily minor scratch
marks. I checked the system out next day (dry conditions) & all appeared normal except the sound level of the rear warning was much lower than the front.Any ideas,it seems to me that the rear volume is more important.
