    Scanned the car today briefly with VCDS Lite, but I think my KKL lead is goosed. Been tempramental for some time now.

    Anyway the codes are:

    16518 P0134: O2 Sensor Circ.,Bank1-Sensor1 No Activity Detected
    16538 P0154: O2 Sensor Circ.,Bank2-Sensor1 No Activity Detected
    17967 P1559: Idle Speed Contr.Throttle Pos. Adaptation Malfunction
    17973 P1565: Idle Speed Control Throttle Position lower limit not attained

    So the dose of Cataclean only works for 2.5k miles!

    So I need to replace both Lambdas.

    How to solve the other two?

    Some of you may remember, a short while ago, I posted about poor MPG. It was around the 25 mark. Now, the car will do an average of 30.9MPG (according to the DIS) on a journey to and from work. Would this improvement be of any effect from the lambda's failing?

    Clear them and see if they return?

    The throttle ones are probably a result of the tracks on the PCB becoming dirty.

    You might get away with just removing and cleaning them.

    Bought an eBay special obd lead yesterday at 15:45pm. At 09:35 this morning it arrived!! Now thats service for £7.89!!

    Anyway, it installed a treat on windows 7 with vcds lite.

    Re-scanned the car and only two codes came back on which were the throttle ones. Lambda's has stayed off for now?

    Can I do the throttle adaption on my car does anyone know??
