Current situation is Audi A4 Avant, 12 plate, 84k miles, 90% motorway miles. Accelerating on Saturday and still an issue in 3/4/5/6 revs jump up by about 300 RPM then drop back down by 300 RPM car then starts to accelerate as REVS increase. Car then seems to pull ok after that.

Car booked in to main dealer next week for inspection. A local indy is quoting to replace clutch, DMF and seal after a test drive (ouch), also said there is a slight judder during acceleration which I have not noticed but will look out for next time I drive it. Annoyingly the car is 3 months out of warrenty....

Does this sound like a diagnosis and fix for the issue for a car that only done 84K?
