Is it possible that that damn workshop has interchanged the 3 chain tensioners (so they are not in there original position) and that is causing the engine to vibrate at higher rpms?
Thanks, Markus

What's a dmf?
The cams have to be locked down when the ims is replaced - if they didn't do this then the timing could be all off. I'm not sure if that would cause a vibration but it would definitely run rough (and you wouldn't have much power from the motor either)
Does the vibration happen with the clutch pressed in and revving the motor? If it doesn't, Could the clutch be off balance and that's causing the vibration?
