okay so i have a a 2000 a4 quattro T. and im having a hell of time with it starting. once maybe twice every 3 weeks, approximately, it will not start, it will make the sounds most all engines make right before the start, but with mine it can go for minutes. and it never happened during the winter, i have replaced the spark plugs, and electrical connectors, and when i pulled out the spark plugs they were covered in oil. any suggestions from people with this probelem, or know what to do? and once it starts there are zero problems, all the lights/electrical stuff is good. is there a warm up cool down routine that i should adopt, i do let it cool down and warm up before i drive it.
