anyone else have a faulty thermometer? I have a 200 328Ci which I have had for about a year and one day I noticed that the temp of the car was up at the red section (about 2 o'clock). So I stopped the car and restarted the engine. The gauge went to about 11 o'clock. I called the dealer and they said that the temp gauge was faulty. anyway, has anyone else had this problem?
