After reading all the problems the X5s are having with this issue, I decided to us some preventing maintenance. This is what I do every year:

1. Right after the first month of freezing temperature, i will take the CCV off and clean it.

2. Since I drive the X5 to work every day and the job is only 15 miles away (not enough to burn the condensation), I use a Vacuum to suck milky stuff that may be accumulating in the CCV. I can tell it is clean when i see black oil coming up the tube.

See pictures below.

I hope this help.
