In need of help as about to give up - car is a Octavia Scout 66 plate 184hp DSG - I had the DMF replaced in November 2020 at 101,000 miles after it failed on a motorway trip by an Automatic specialist, which was sodds law as the warranty had just run out. Ever since it was replaced I've had issues with vibration worse between 1-2k rpm on acceleration and on deceleration as it goes back through the gears. Vibration is deep in tone but loud and comes through the seat but is mainly coming from the back of engine and through the floor like its coming from the gearbox.
No noise from the Haldex or the back of the car except the normal slight whine.
Its gone back into the Indy this week for the 4th time since the DMF was replaced but both him and I are slightly clueless as to what it could be. Any suggestions would be great?
