Many thanks Glenn. Could you please be more specific on the location of said sensor? Is it on the pump at the front l/h side of the engine looking from the front of the car, behind the EGR pipe
One of these? Delphi Inlet Metering Valve IMV Fuel Pressure Regulator Sensor 9109-903 from fleabay.
Forgot it's mk3 mondy 2007, last of the mk3 TDCi
Cheers
Barrie
