    Hey guys. My A3 1.8T 8L has a issue that is baffling me. Basicly when i first start my car, the auto choke kicks in and it revs at 2000rpm then when it gets warm after 5 mins the revs drop down to normal 850rpm. If i turn the engine off and start it again straight away, the revs go back upto 2000 like its cold..

    Any ideas?

    an 1.8 t doesnt have a choke, it has a cold start fuel inrichment system, so with that in mind id replace the coolant temp sensor and see if that changes it at all
