Vacuum leak; checky your CCV - The BMW 5 Series (E39) Message Forum

Might be a CCV error; diaphram failure. I have reard that you can check if a leak exists by opening the oil full port and use a vacuum gauge to check for vacuum. But is there a device that can be bought/rented to do this and what is the right crank case vacuum reading?
