Haven't hear that on our C320 4matic. Do you think it's a tranny noise or more of a differential noise?Every once in a while I get a brief whiring type of noise, like gears spinning, coming from the front end on my 03 C240 4MATIC. Any ideas?
All it does is start the car off in 2nd gear. I frequently use that mode (it's called "Comfort" mode in the S-class, heh) when driving around passengers since it provides for slightly smoother starts.do you have the A/C on? is it in W mode? I havent heard this noise on our 320. When i drive it again, ill try and listen for one.
