Hi,
maybe someone has a good idea - my mechanics can't find the reason.
Mercedes W221 - I have vibrations at motorway speeds (over 65 mph) only when I put my foot off the acceleration pedal. When I accelerate everything is good. on the speeds below 60 mph, everything is nice and smooth.
So far, we checked tires (new ones, Dunlop, fitted 2 months ago), wheel balance, engine mounts are new, rear flex disc on propeller shaft is new as well (engine mounts and flex disc were changed after the problem with vibrations occurred).
a bit earlier (before the problem) I have changed wheel bearings (front), tie rods and tie rods ends, drop links.
the torque converter was fixed (renewed) - before it was shaking the car when I was accelerating.
any thoughts? Mechanics checked the car twice and they have no idea where to look next...
