AlgarveVR6 0 Posted January 9, 2008 Sounds like temp sensor to me. Mine was shitte for a while. Turned out to be Blue Temp Sensor. ECU has three default settings if it's f / #"/%. Means the ecu thinks its -49 degrees for first few mins, then 20 degrees for a while then 77 degrees, and sets fuel etc for those temps Vag com will tell you. I bought a lead from ebay and downloaded the shareware from ross tech. Best 20 quid i ever spent. have fun, and don't worry, the new sensor is about 10 quid. Cheap fix for a C Dic Quote Share this post Link to post Share on other sites

voo51 0 Posted February 11, 2008 Just wondered if you got it sorted and what the problem was as mines got similar symptoms. Quote Share this post Link to post Share on other sites
AlgarveVR6 0 Posted August 21, 2008 If its a 16v, try the cold start valve. My wifes C is a 2 16v and her cold start valve has gone. The 2 16v does not have a blue temp sensor.(I don't think) After about 5 mins, the car warms up and runs like a peach. Have fun Dic Quote Share this post Link to post Share on other sites
