Car revving on its own – what to do?
VW 412 Variant

    My car is revving on its own, going from around 1,200 pm to 1,800. I’ve had the throttle body cleaned and repositioned by a VW specialist twice. Any thoughts? The fault codes I’m getting are P1553, P1172, and P1543.

    Try checking the crankcase ventilation hose that goes from the inlet manifold to the breather unit at the back of the engine.
