Yeah, that's the one we tell everyone to be super careful with because if you break it, you've got a nasty CVV job ahead of you.

this pipe runs way down in and connects to the oil separator. There is a huge DIY for replacing this CVV which entails the separator and its four pipes.
people complain bitterly about this job, but if you set aside the time and have patience, I actually enjoyed it.
Of course you're now forced to deal with it rather then it being an elective where you can schedule your time and wait for warm weather.

BTW, best for you to do the entire job as if this pipe is brittle, the rest of this system is probably due.
Do you have good service records?

You broke pipe #2

You could use a piece of hose to reconnect the longer part with the piece that connects to the valve cover as a temporary solution (I may or may not have done this myself ) You just have to make sure it is sealed enough that it won't leak.

Not easy. It connects to the CCV. Review that DIY to understand why.

It's buried way deep down and layers of stuff has to come off to connect.

Don't feel worried! That hose is one of the 4 oil lines connected to the CCV. The hose had to be pretty brittle for you to snap. A brittle hose means that your Crank Case Ventilation (CCV) and the hoses connected to it is old enough to be changed. You might as well DIY the CCV and get it out of the way. One of my oil lines tore apart and I was left with a Service Engine Soon Light and lean codes for the longest time. It's a tedious task, but doable if you have patience. Search for 2-3 DIY threads, study it, and do it. That's after you order the parts of course. Parts run from 150-200. DIY time for me was 6 hours with breaks.

Just do a catch can nd save yourself the hassle.

The other options are replace the CVV. (I have a practically brand new valve, you can have it).

The other option is to get a piece of 3/4 tube and some clamps. Slide it over the hose and GENTLY clamp it down. Then run the other end to the valve cover and clamp it over the connection till you can get another hose.

How many miles do you have on your car? If you haven't replaced the CCV, this is a good sign to replace all the hoses. You can replace just that hose, but if that hose is that brittle, the others are pretty much the same.

You can buy the "Crank Case Ventilation" kit. I would recommend Genuine BMW. This is where you do not want to go cheap. This will take about a couple of hours. Good luck.

Here's a video just in case you decide to do the DIY: http://blog.bavauto.com/8003/diy-vid...lation-system/
