    004759 - Pressure drop between turbo and throttle valve - (Check DV.)
    P1297


    004244 - Bank 2; Fuel measuring system 2.
    P1094


    001300 - Sensor for battery temperature.
    P0514

    Checked fuel pressure as per Ross-tech wiki but not a clue what figures should be compared to figures I have.

    Anyone got any ideas, car has a very lumpy idle, this has only happened since leaving work tonight. Other than the idle it drives fine, don't want to drive too far tho incase I'm causing more damage.

    First thought was a coil pack, but any gone on previous cars all go under load and this is fine.

    Cleared the errors and only the 1st error comes back on idle. Had the engine cover / airbox off to check for split hoses. I also checked the PCV by opening the oil cap with engine running, a suck and release of air suggest PCV so going to swap that tomorrow as symptoms seem similar from online faults.

    Changed the PCV valve and gasket today £51 from TPS and appears to be solved, cleared errors, test drive and still no errors so all good.

    PCV Valve - 06F 129 101 N (Is a revision P but doesn't work on older stuff)
    PCV Gasket - 06F 103 483 E
