Anyone near Gainsborough got a fault code reader?

MIL has come on but goes back off again when ignition is turned off then back on again. Happens about once a week but more frequently the higher the dial is set on the Synergy 2

Set on number 8 it came on 3 times in 10 minutes and goes into limp home mode, struggling to rev above 2000 rpm.

Have plugged in my vagcom and it says one fault registered against the engine but doesnt say what.

Beer tokens waiting for someone I can bring it to to read the fault for me.......

Did it do this before you fitted the synergy?
Have you checked the contacts are clean on the high pressure fuel sensor?

Took it to Maltings Off Road, diagnosed it as low fuel rail pressure. Getting the pump changed on Friday.

Thanks,
