heavy grinding noise during hard acceleration
Hey everyone ! I've got a 2014 cls63s and today after driving it about 35 minutes or so i noticed a heavy loud grinding noise coming from underneath.
it only happens during hard acceleration, it sounds like my exhaust or a piece of metal is being dragged against the floor. I stopped the car at a parking lot nearby to take a peak below
everything seems to be intact. nothing is hanging loose or anything. Normal driving is completely fine no noises at all. As soon as push the pedal a little bit the grinding noise comes back on.
no engine light I'm confused ... car is tuned res delete and has Upd filter+ spacer. I drive the car hard.
any help will be appreciated.
