Unfortunately BMW's Achilles heel is the cooling system. Factory plastic expansion tanks are known to crack, explode or the plastic nipple for the return line breaks off. If your N52/N54 has a plastic expansion tank and it is still intact after years of heat cycling, consider yourself lucky - however, it is not a question of whether or not it will fail, it is a question of when it will fail.
