Hello all,
I've finally purchased my first BMW since I was 18. However I'm in a bad spot and could use some help.

I bought a 2005 BMW x3 3.0. It was a great deal. However, right after I bought it, the crankcase separator started messing up. I'm in the process of trying to purchase the parts to have it replaced. My questions are...

1. From what I can tell, it's best to replace the hoses along with the assembly. Are there any other parts that I should buy and replace while I'm in there? Where can I find all the parts?

2. Where is the best and least expensive place to buy the parts (hopefully this is answered with question 1 )?

3. How do I know if it's a cold climate model?

Any help would be great.

thanks
