DSG oil & filter was done at 40k, and I've literally done it again about 500 miles ago (53k). Have done a couple of DSG resets / adaptation procedures and it makes it better for a while but generally finds itself back to where it was over a week or so.
I got a warranty with the Mechatronics fix but I think what I'm seeing is a different problem to the well known "jerking" in 1st and reverse which the guys at Bristol Gearbox Centre sorted out (replaced faulty solenoid).
I'm pretty much near the centre of Wycombe. Who did you have in mind? Are you local too? PM sent.
