I can replace the Oil Separator as it is - get new hoses, etc and clean up the oil mess and possible blown gaskets - all for relatively cheap.

or

I can get the special winter kit that BMW is selling for the X5 that has a heated Separator and insulated hoses - thus increasing the parts costs and the labour.

From what I have read - the separator is not the easiest thing to replace - the 3/8" return line being a PITA. I have a call in to the local Midas, who has all the technical manuals and have worked on BMWs before - we'll see if they want to take on the challenge.

Right now my X5 is sitting in my garage, slowly leaking off the chasis the 6 liters of oil it has vented overboard (yes I have replaced it, just not cleaned up underneath.) My biggest issue with not getting under the hood and doing it myself is that the ambient air outside is about -15F with the garage hovering around freezing.

Zoomie, You can buy the updated part from BMW that has the insulated seperator. Then have that shop change it. Given your cold climate i would definitely get the updated part. Otherwise you may be doing this every other winter.

Also, If you change it in your garage I know the temperature is hovering around freezing but you could still do it. If it bothers you that much, I would just buy a little space heater and put it in the garage a few hours before you start with the car parked there. That way your garage will be at comfortable temps when doing the job...

If you opt to just get the seperator replaced and not get the updated insulated seperator, i would reccomend you switching to 0w-40 oil during the cold months up there. This oil is more cold friendly on your engine..
