"1995 525i auto and car runs great, smooth
problem #1 is about once every one to weeks I will get the add coolent on my display, either right when i turn the car off or right when I turn the car on, but never while driving. I check it out and the coolent is low about 3-4 inches , where is it going, I park in a garage and no leaks and as far as i can tell it's not getting burnt, (Checking smell and look at the exhaust while running) and the needle on my tep gauge never over heats , it's right in the middle once warmed up, thats where it's supposed to be rgiht? any ideas on this?"

On #1 - I had a very slow coolant leak in my heatrer core which until it developed into a little more substantial leak went undetected. Right now I have the heater core bypassed until I have time to fix it.
