The DSG software was updated and not fixed. One theory I just had from the independent VW specialist is it could be the Duel Mass Flywheel, symptoms sound right as feels like 'slack' between first and second gear pull away and down shift!
Booked in with them tomorrow to get their view!
Updating the software is not the same as resetting it. When you reset it you have to do multiple sequences of driving, like 0-100mph, 70-0mph emerncy stop, cruise in one gear for 3 miles and loads more.
It reset's the link between DSG box and the ECU. And as far as ive been told, the DSG rest should be done after every software update anyways.
You seriously might want to try it before you buy any mechanical parts mate
