air in diesel fuel lines - r reg Polo - Scampy
Had similar problem for 2 months , went to diesel specialist who had also had his fingers burnt as well with same pbroblem. 1st thing he said was change the fuel filter for Bosch N6172 and bypass the plastic return fitting to the filter by joining the return lines together. This is how the air gets in. No problems since
