We got in a Q7 3.0tdi year 2011 that was running but with fault low fuel pressure.
Local VW dealer changed High pressure pump, and after that they could not get it running. They don`t have Audi license anymore so they could not do any adaptations on it they said, so they have given up get it running after one week...
I have now updated it to the newest Audi SW version, can clear fault codes on engine, but once I try to start it they come back, also not starting either.
Fault codes are no power to injector bank A and B, P2146 and P2149. They are cleared in the autoscan, but attached after that.
Anyone know what next step is to try? Or what could cause this? Car was running after all before they changed the pump.
Thanks in advance if anyone could help here.
