    hi guys, my 320ci has developed an intermittent fault that puts the car into limp mode, eml light on, traction control light on, revs itself up to 1500 revs and no more, so barely moves !

    my mate who works for bmw says it could be the throttle body sensor +/- the the engine wiring loom coroding, sounds expensive !

    read up on this and it seems a common fault

    my question is is it possible to cut the loom wires back and respade them and put the plug back together to save buying a new loom ???

    which models are the looms the same on, mine is a 320ci petrol 51 plate

    cheers

    The first thing to do would be to have the codes read-see what faults are stored on the ECU

    Yes, that sounds like the emergency mode for when the throttle position sensors become unreliable.
    Wiring is possible, as is the throttle itself, the sensor isn't changeable by itself, so see if you can spot a problem in the wires as otherwise it's a complete throttle assembly.
