• @Fixedwheelnut any ideas on Fuel Injection System Error fault showing on a 2002 E39 525d?

    Car ran totally fine but the error came up after some moderately aggressive driving on the M25. Not fast, but a bit of repeated heavy acceleration involving the kickdown switch at the end of the pedal travel. I slowed right down and luckily South Mimms was only a few miles away so pulled in there and had a rest and a look under the bonnet. Nothing to see there, and when I turned it back on after 10 mins, the fault had disappeared.

    Quick Google suggest fuel pump could be on its way out but if you have any other thoughts? Worth just plugging a fault code reader in and seeing what it says?

  • Fault reader to see what it says, it could be an Air Mass Fault, due to air leak, or EGR fault
    edit; they are very prone to vacuum pipes perishing with the heat under the bonnet affecting turbo operation.
