Thanks for sharing... Happy everything worked out for you bro. I was following the original thread and was like dang, so many errors...

Thanks for the info; I’ll be waiting for the images of the item replaced. My car is 08, 528i N52 and have replaced few things trying to solve rough idle and now I am getting randomly cylinders misfires on different cylinders every morning without any engine light come on yet.

thanks for sharing, my car this morning said Increased Emissions. I will have to take a look at this over the weekend.

UPDATE: There is an elbow joint at the bottom of the vacuum pump that the mechanic thought was the problem, it's a $12 part that gets brittle with age and cracks easily. However, it turned out that my vacuum pump itself cracked in half, so the repair was a little more than originally thought ($160), still very reasonable considering the alternatives (O2 sensor = $150 each X 3, Secondary Air Pump ~$200, Coil packs $35 X 6, etc). I will post pics later.

Okay, here is what happened to my car:
First, this is what your vacuum pump is supposed to look like:


Here is what mine looked like:




Here is the elbow the mechanic thought was the issue at first, he said it gets brittle over time and can crack:


Lastly, I have an elbow running from my Secondary Air Pump to the motor, that for some reason was held together with electrical tape. The mechanic replaced that one as well as a precaution:

LOL, yup, and based on the errors the car was showing they would've changed all my coil packs, my O2 sensors, my secondary air pump, and STILL not fixed the issue.
