oil separator changed, though questions open

[Zoomie]

Thanks again guys for the good information.

I contacted BMW parts and got this in reply:

A COLD WEATHER KIT FOR AN X5 IS $729.00. IT INCLUDES NEW INSULATED HOSES,
INSULATED SEPARATOR, AND DIPSTICK TUBE.

It doesn't mention the "heated wrap with cable" (Part # 11610390846) which other SIB's specify. I wonder if it is the insulated hoses that they quoted above. I remember reading one of the many posts on here about someone changing out the stock hoses and separator for these insulated ones - I will have to dig that up.
