My suggestion would be to repair the leak before you overheat the car. BMW's don't have a large amount of coolant, so overheating comes fast and you can warp the heads meaning big $$$$$. I'd replace the whole cooling system if you near 100K. water pump, hoses, thermostat assembly, and expansion tank. White dry residue is a sign you are leaking coolant. Adding just water is not a good idea, especially if you are in a colder climate. Go here to get your coolant kit if you want to replace yourself......www.fcpeuro.com

Thanks for your input but what i need to know is if that engine burns the water or is it a head gasket problem before i take it to a dealer and get ripped off i already fixed the leak but still see myself putting water every couple of days
