7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Alot of air codes

Hello! I have been checking around my engine today for a vacuum leak without finding one. Used crc break cleaner. So i moved on to my next problem, that was a oil leak. It was leaking on the passenger front side of the engine, so i took the fan out for a closer look. Turned out to be a faulty seal on the vacuum pump. Just ordered a new sealkit for the pump now. Anyways, my question is. Could it be the faulty sealing on the vacuum pump that is throwing this codes?
My symtpoms are: missfires, engine light, hard to start when the car sits still for a few hours, rough idle etc.

Looks like DISA related issue. I know that a failed CCV system can cause oil residue to build up in the intake manifold and cause the flaps to stick and burn the DISA motor out. That's my guess
