So unless you were in sub freezing weather (i.e. <-11c for awhile) when the warning came on, 'All did [NOT] come up negative'. You and your dealer just don't know it yet

We had this happen in December in our ML. It got down to -40 and we were told the pump froze. Hopefully we don't have the same problem in our X5.
