I have took my car to audi to find why it is misfiring, its not plugs or coilpacks but the head has to be taken off i know its gona cost over £1k im labor in stripping and putting back together. Has anyone had a new valve if so how much was it from audi? I have told them to go ahead with the job now so no going back. Ive been told a flap in the inlet manifold has possibly snapped off and got in the valves. Also if this is what it turns out to be anyone know cost on these parts and fitted?
thanks
