Good thing too, as this heated wrap seems to be another point of failure:

That recall is for 2006/8/9-2011. Not going to affect our E53 line. We have the old CCV system prone to freezing the mayo if it is present. Best thing to avoid in frigid temperatures is short drives. The condensation never gets burned off and fills the separator with oil water mix. (mayo)
