I can ask him to look when he's back next week - My works Pool Car - Seat Leon 1.5T Petrol does it sometimes better now with a few miles on itIs your Mastertech friend able to shed any light on the possible cause of the juddering and a solution to that which some of us are experiencing with our cars ? I've read in other places that the 7 speed dry clutch s-tronic (mated to the 35tfsi) is only good for cars that produce under 250nm of torque. Audi's literature states 35's provide 250nm to start with. I think I've also read the MHEV can provide an extra 50nm's.
I would suggest you try a couple of tanks of High Octane fuel to see if that helps as well
