    V40 - Diagnosis of fault codes

    Had the following:
    P0103 - powertrain
    Mass or Volume air flow Circuit High input

    P0420 - powertrain
    Catalyst system efficiency below threhhold(bank 1)

    P0243 - powertrain
    Turbo/Supercharger Wastegate Solenoid "A"

    P0171 - Powertrain
    System too lean(Bank 1)

    P1513 - Powertrain
    (Multiple descriptions)

    I'm ignoring the CAT issue as it doesn't have a CAT (sssh) and the reference to Bank 1 as it is a generic reader (Torque APP) and therefore might have a setting for V8s etc.

    I'm guessing that P0104 is the MAF playing up. I have now fitted it the right way round and have a spare to try.

    I'm not sure of the last three...Any ideas??

    I think I need to get my AFR gauge fitted.
