Re: Code 56?
Alrighty, found the Vacuum Sensor, it is the one under the ECM. When I unplugged the vacuum line, I heard it release the vacuum. So it is holding vacuum properly.
Anyone had one of these fail?

Code 56?
Just got done putting her all back together after replacing the secondary vacuum solenoid under the plenum.
I get code 56 now. Searched and can't find any reference to it at all.

I can only speak from BMW experience, but to answer your question, no.

Re: Retrofitted HUD
It's not needed, but highly recommended to get the best clarity/brightness out of the image.
