I have an 05.5 Jetta BRM with DSG that I have just spent a bunch of money on and now have another issue. It will shudder under a moderate to hard acceleration, especially at lower RPM's. I has just gotten a new DMF, new Stock Camshaft (until the Colt Billet Cam comes in), new PD 140 Turbo, timing belt, water pump and serviced the DSG. I just adjusted the cam torsion last week as well. It was at -0.5, now at 2.0. Just had 4 new tires and alignment done yesterday. The car drives wonderfully now except for that "new" shudder. I'm thinking maybe the clutch pack in the DSG is the cause. Anyone else ever have this issue?
