I am having the same problem, when I take the cap off the expansion bottle the air goes in and the level rises to overflowing. I have done a pressure test and there are no leaks, I've changed the expansion bottle and the fan relay switch but I'm still getting the same problem. My fan comes on when I turn on the A/C but won't come on when the engine gets up to temperature the it over heats. My my mechanic is sure it's not a head problem as there are no gasses in the bottle. Any help on this issue would be greatly appreciated. V40 2014 61000 miles.
