I'm in Uttoxeter (just West of Derby) if you ever get near there and I have full vag com. I could carry out your throttle body adaptation and run a diagnostic test as well as any other coding you may desire
I’m probably a little closer than Rob, although my VCDS knowledge is no where near as superior as @chumsofmanutd. If you’re after a scan to understand a problem then I can certainly help. If it’s anything beyond that that then I really do recommend a drive to WOM Automotive.
