i promise this will be my last post about the idle, when cold its ok when warm it idles anywhere between 500-650rpm hunting. ive now run out of ideas - new lambda sensor, new leads, new dizzy, tried several idle control valves, tried another throttle body, tried another inlet manifold, sprayed engine to too see if theres any air leaks, replaced all vaccum hoses at back where idle valve is, new temperature senders, cleaned the MAF and tonyvrt has had it on VAG COM and there are no fault codes. :-(
