been having problems with the car, fuel pressure jumping from good 120+ pressure to as low as 7 bar at the rail.
i was told a fuel relief valve on the fuel rail maybe at fault. i bought part from audi at 19+vat. its a threaded piece that goes in below the inlet manifold and accepts fuel line. I havnt changed it yet as it looks in an awkward place!
anyone had to change one of these before?
I looked to change the sensor/valve on top of the fuel pump (32mm spanner fixing), but they said this comes complete with a fuel pump only?
current fault code reads Low fuel pressure.
Help, im missing the car big time!
