If you put the indicator on it will alternate between flashes at normal speed and flashing very fast. The car has a towbar fitted (a factory removable one I think) which I had the same issue. M54. I had pressure in the system (which does not help in this case. head gasket replacement under way) and "stop leak" in my heater resulted in no heat. You need to check your system for air, coolant pressure and stop leak. Air is easy. stop leak - you need to flush the heater.

Hi - I have a 1999 323I Automatic Tranny. The console area where the shifter is is the problem.

P shows as 2, Drive shows as ALL lights except The extra resistance due to one bulb circuit being broken causes the flasher to increase its rate.
