I've had this problem ever since having my 54 plate B6 Audi 1.9 TDi AVF 130bhp PD A4 Avant. It's always been a poor runner for the first 5-10seconds of a COLD start. Never does the issue occur after a warm start or even if the car was used say in the morning and you use it in the afternoon. It's ALWAYS when left overnight.
I have Audi a4 B7 Quattro 2007 It starts sometimes perfectly, but there are days it won't start?!Connected computer and it says the fuel pump problem. change the fuel pump it started and worked for 10min and then had the same problem? check all the fuses they are all fine the computer gives me an error code P3073 any information will help
