My coolant light is coming on when I first start the car and then it goes off after the car warms up a little. I bought some coolant at Advanced Auto Parts but have no clue where the overflow access is for the coolant fluid. Can anyone help guide me in the right direction?

You should be able to add coolant into the radiator. There is an easily accessible cap. If you are still having problems, I would strongly recommend visiting a BMW shop. You don't want to mess around with cooling system problems on a BMW, as if problems exist or persist, you could create massively expensive repairs.

You might also check the lower coolent temp sensor. I had the same problem and kept adding coolent while looking for the leak. The gasket on the sensor goes bad and it just drips a little at a time till it gets hot then stops. Its only 23 bucks and took 5 min to change
