I've just had the two front suspension struts replaced on my 8000 ml. E 220 AMG Coupe 2014 I had noticed a clunk from the front when reversing to the right, I took it back three times to MB dealer he could find nothing wrong, eventually he rang Mercedes who had heard of this a few times on this their latest coupe, fortunately it was fixed under warranty, but it seems to me, perhaps Mercedes have got some fault in their build quality, Have any others on here had this problem?
