Check out this diagram on real OEM:

Part #2 in the diagram, it's called the Leak Diagnosis Pump, $112.36.

It's for a 328i (my car) because I just punched the last 7 digits of my serial #, but this applies to your car just the same, I checked.
I replaced this on my X5 back in August as I was getting the SES light that's now gone.

Good luck!
