did your dsg box go bang 
Nope - it developed a proper clunk, which VW said is totally normal.
It also engaged drive when in park when I turned the car on - "normal behaviour"
My issue was with the way I was spoken to. I noticed rust on both arches (front) and naturally tried to claim under the 12 year corrosion guarantee. Apparantely the rust is classed as a "mechanical issue" and not covered.
I tried to claim and was told they would give me 50% goodwill contribution, which was bad enough. I questioned why I didn't get the full 100% and was told "it's because we don't class you as a valued customer, sir". I raised a complaint (whilst doing this I was actually negotiating a deal on a MK6 GTD). I mentioned that for the sake of an apology and what amounts to £250 of VW's money (I would have taken 75% as a gesture of good will) they were about to lose a long time customer and a sale of £16,000+
They basically said "sorry you feel that way sir, I hope you enjoy your New car and hope that you'll come back to VW one day". Complaint closed.
There's more to it than that, but that's the general overview.
