Thanks all. It's starting to become a bit of an uphill struggle with VW and the dealers and making me re-consider getting another Golf although I'd imagine most manufacturers/main stealers are the same across the board.
FBASH1R - I'll send you an email although they reckon they've tested the fuel pump on multiple occassions and ruled that out. It also doesn't happen all the time which is strange and would make me wonder if it is the pump. Be interesting to see yours though.
