I have a 95 740i, 150,000 miles, making a thump, thump noise every 3 seconds or so. It seems related to the heater. I can smell a strong odor of antifreeze coolant when the heater is turned on. Also the Check Coolant warning comes on within one week of adding a couple of ounces of coolant to the reserve. Been going on for weeks now. Any comments anyone?
