If the wire loom for the oil sensor is leaking, change that 1st. Around 12.00 to 15.00 at your local BMW dealer. The vacuum pump is around 20 to 60 minutes to remove, based on your skill level. You will need female torx sockets to remove the bolts. l will post a link for the removal. Get some engine cleaner & remove all oil possible, to make sure you can watch the oil leak.

Good Luck!
