My coolant light had come up on the dash and sure enough, the coolant was low. I topped it off a couple of times, but each refill leaked out. Replaced the Coolant Expansion Tank and the fluid level has maintained. Reused the old cap. This expansion tank even came with a new coolant level sensor. I stashed the old expansion tank in case I need to salvage the sensor or float from it in the future. Cleanest part under the hood now ;)

I purchased a replacement coolant reservoir tank for my 08 BMW 335xi (e90/n54) and it fit great, even the old cap switched over no-problem. My only issue with it is that a tool designed to work as an OEM BMW radiator cap for testing coolant system pressure, does not fit all the way down as the inner-dimension of the cap-hole is not as deep as it was on the from-the-dealership OEM reservoir tank. I managed to re-purpose a GM radiator pressure test cap to work, but the BMW specific one just can't screw on because the tank is just off from true OEM status. Other than that, it fits great into position, looks good, and doesn't leak!
