My mother has an old 2001 1.8T 225bhp Quattro Roadster which she just wont get rid of as she loves it so much, trouble is it never starts first turn of the key but try it a second time and its absolutely perfect every time. Its almost like the fuel runs back to the tank overnight so it takes a second load of cranking to get it back to the fuel rail. I have no idea what could cause this? Any ideas
