Have you changed the sparks and plug coils?
Rob at Autotec was very careful to explain why you should put new plugs in, plug coils too - you'll probably find that the leftmost has corrosion down the hole. Apparently this is common. My old 3.2 had issues with broken coils too so maybe a theme there. Awseome GTI do a good deal for just over £100 the lot.
Thanks mate plugs have already been changed to colder plugs and regapped I have ordered r8 red coils through a place called psi tuning who deal in Vag stuff and they were much and such the same as awesome plus I ordered uprated prop bolts from them to so got postage discount to.
I'll keeps you's posted with how I get on
