Hi all

I have checked the injector leak back both hot and cold and over several rev ranges to find all ok, replace fuel filter, vacuumed filter head for possible air leaks and blown through fuel pipes from tank / visually checked them. After reading about a "known issue" on autodata I have replaced the fuel metering device in the high pressure fuel pump. However the fault still remains that it will start ok and drive if your steady, if you accelerate sharply it logs the fault and returns to idle or stalls, watching the live data from the fuel pressure sensor it looks ok however not yet managed ( due to time) to scope the readings direct. My question is - has anyone ever had either fuel pump or pressure relief valve issues with these models ?

Many thanks - will report back with findings as they appear !
