thanks for the input, I might need to bring it into the dealership to have them top it off, hopefully they don't charge me an arm and a leg just to do that as I recall that bmw uses a special phosphate free type of coolant..... but does anyone else have any inputs as to why it happens only when the engine is cold? would it be some sort of ticking time bomb before something major goes and its a $1000 plus repair??
