Can't you get it mapped at APR in Milton Keynes
That's what I wanted to do bud, but when I spoke to Evan at APR, he said they had moved there "European office" to Germany!! That sucks! So uk one is closed.
I've been using them since I got my GTI a few years ago and a lot more often since I bought my TDI **cough** LEMON to save money which has ended up needed everything bar the ashtray replacing. Fantastic service by genuine enthusiasts - The best VAG specialists around Northampton IMO 
Cheers for the reassurance! They seem like genuine enthusiasts, so hopefully can find a trusted, fairly local garage to look after me!
