I have a Cupra 290 2016 25000 miles ( stock). I have started to get a slight thumping noise coming from the drivetrain when coming on and off boost, it’s not bad but it has become noticeable. I fitted a 034 lower dog mount insert about a year ago to cure the wheel tramping which I have noticed has started to creep back under spirited driving. I believe there is obviously something wrong with one of the mounts and would like a garage that actually knows these cars and has a wealth of experience, but I can’t seem to find anyone in Essex, any ideas or suggestions would be greatly appreciated
