Looking at a 2002 530i and seems to be a coolant problem. Seems coolant is shooting up through the overflow hole next to the cap like there is too much in it but the check coolant level light keeps coming on and after a few miles of driving and I start to lose heat. Temp guage never went above halfway? Any ideas? Buy the way I'm a newbe and just wanted to say hey to all of you! Also have a 2001 X5 that the wife drives and we love it!
