Hey everyone! I've recently bought a S3 for winter runabout whilst my BM is garaged as I thought it would be stupid to use to a RWD convertible in winter however I have a couple of issues with this vehicle. The problems I am having are for example Number 1: If i drive around with the heaters off completely, the temperature gauge would sit at 90oc with no issues but the moment I turn the heaters on, they would drop almost to 0 on the temp gauge. -Fault coolant sensor? or anything common? Number 2: Just today bearing in mind the temperature being around +3 or could be less, I've currently being experiencing some starting problems. I would turn the key to start but its like its hesitating and finally when it does start the revs would rise above 1k then go back down. Now I don't know if this relates to number 1 however sometimes even when driving around for ages, and i turn the engine off for 5minutes then turn back on, its like the engines rpm rises above 1k like its a cold start?. I was thinking this maybe MAF related however I am not sure if it is or if its just because of the cold temperature we are currently experiencing. I did disconnect the maf and I thought it shouldn't start without the MAF however it did which is why I'm thinking its most likely using the MAFs last default reading? I know MAFs are like sensors and can get dirty, however is there anyway I can clean it or what is the cost of a replacement. Lastly back in August, I had a 2002 Audi TT 225 cab which I heard Audi was doing the coilpack recall- is this still on? Its a 2001 '51' AMK S3. Any help/comments would be grateful Thanks in advance P.S what are the most common performance mods? I remember seeing n249 delete or something like that ages ago when I had my TT lol. Just wanted it to be running a little more HP.
