A4 2tdi S Line Judder

[Strontium dogs]

Could someone please help, my Audi judders in second and third gear. Low revs or foot down its fine but when i just cruise it judder in gear and a bit hesitant.

I was going to go to main dealer but dont want to be conned in to having a new clutch if it isnt the clutch!

Cheers guys
