m62 vanos issues
 

I realize that this is old hat for a lot of you but my 740il has codes 165 and 33 when I read them with my old snap on red brick and I was hoping some one could give me the best approach for repair. In NC the car won't pass emissions testing with the ses light on I have tested the solenoid and cleaned screens but now I am afraid there is a blown seal in the vanos unit itself any input will be appreciated
