Did test runs and my hot/cold meter was quarter way being overheated ! The engine sucked all the coolant so I filled once again. Did same problem. Filled again same thing but this time my hot and cold meter was in the middle. The engine keeps sucking all the coolant. Whut do I do ? How much coolant do I keep adding ? Friends and family says it takes time to cycle. HELP !!!

I've had 740il for a year and a half been blessed so far but now it doesn't start on the first turn , sometimes it takes three or four tries to get her started. and she has also stalled out on me twice. thanks

My 2001 740IL every once in a while will blow out a cloud of blue smoke from the exhaust when starting the engine. This happens no matter if the oil was just changed or if due for an oil change. I have the car serviced at a qualified European auto mechanic and use the prescribed synthetic oil. Any ideas as to what may cause this?
Thanks
