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

You ask if the shop interchanged the tensioners, but replacing tensioners isn't on your list of work performed.
I'm somewhat confused by that. Did they replace tensioners?
I'd focus on what they changed/ touched.
Why did you replace the dmf? What were you trying to solve? Was it replaced with an oem unit? Was it new or used?
Ike asks a very good question: clutch pedal in or out, any change?
