    Hi Guys.
    Has anybody any experience of faulty throttle body's on these motors?
    Fault codes as follows:
    28D7 - unknown fault
    279A - Throttle valve control unit Error w/repeated learning process.
    2785 - Throttle valve position sensor malfunction.
    2787 - Throttle valve position sensor channel 2 sig improbable.
    2786 - As above but cannel 1.
    2799 - Throttle valve control unit, error during adaption cancel due to envionmental condition.
    ??????
    All faults sporadic.
    On live data the throttle position and accelerator position signals perfect and work in tandem with each other.
    I cleared these faults and road tested with no problems. The customer didn't even get to to gate of the car park!
    Even with the faults logged the car drives fine.
    Anyone any thoughts.
    TIA - Paul.
