UP28 Pumpe runs with engine off

I have a 2006 V50 with standard engine package. After I shut off the engine a pump continues to run. I think it is a vacuum assistance pump for the breaks. It says "pumpe UP28" on the side of it.

Any ideas what the problem is?

Replace what? If the pump is running it may well be good, but might be commanded by sensors / modules in the car to turn on. Do your due diligence first, THEN start replacing parts...
