russj249 2 Posted February 22, 2012 Report Share Posted February 22, 2012 Sorry to butt in here, but are you on about the 3 sensors in the thermostat housing? Is so (i know its a mk3) but I have an OBD1, with coil and with air-con, but no Brown sensor? Just yellow and blue and a blanking plate thing for the last hole. You sure the Brown is for aircon? :S Link to post Share on other sites
