[Yas]

I'm near Colchester, so north Essex. I would join the M25 at junction 28 Brentwood. I work in north London area near junction 24 of the M25.
HPsauce thanks for the offer and I might take you up on it

I know Marcin as I met him at ADI earlier this year and I think he's in Dartford area which makes him the closest.

The garage I use is owned by a friend of mine and he has vagcom (Rosstech on a laptop) assuming this is the same thing?
I will try him first and see what his diag says, I will post results on here.

Thanks again for your help guys, I just hope it's nothing serious!
