Skoda Octavia 2017 m3 vrs diesel DMF change

Morning all,

Require some help if possible please....

Have a 2017 VRS Diesel which has covered 155k now. It had the dreaded dmf noise at start up like a bag of spanners until clutch depressed. So went ahead with my mate who has looked.after this car for 5 years and changed the clutch and duel mass flywheel...

Got the car back yesterday and it's not right. It doesn't have the noises at start up anymore and would be fixed apart from the dredded juddering at between 1500 -2000rpm especially at high gear under acceleration. The car was remapped some years ago with no issues around the 50k mark. The clutch / dmf are pattern parts from Europarts, my mate also removed the parts and replaced them with another from Europarts incase the clutch was faulty! (Sonit has two yesterday but still the issue) Any help would be appreciated all

Thanks Garry
