I have always had a nasty intermittent rattle coming from passenger footwell area.
After 3 visits to local Mercedes without success they have finally traced the rattle !
With the car up on the lift they showed me the area under passenger side. The protective plate was hitting the floor above when travelling at 65+mph. A common problem apparently .
Resolved by them fitting a Mercedes kit sandwiched in between the plate & floor area .
Now very happy as I like this car.
