Thanks KyleB and NCSU. I hope I'm wrong, but I thought the State somehow electronically tracks the readiness or emissions status through the Inspection Station's computer. I figured that's why they can't just choose to pass the car. I doubt my guy will go for the $50 incentive.
So far, all I know is Actron scanners were used to read the codes. Not sure which models. I see if it passes in a few minutes. I've driven 80 miles with 3 cold starts since it was reset. Still no CEL.
If it doesnt pass I'll replace or clean the Secondary MAF sensor and try to move forward.
Small world NCSUGrad2006. I went to EE Grad school for about a year there. Shouldve studied Automotive Engineering!

In VA, we had to do it every two years and couldn't renew our registrations until we passed the emissions test.
If someone reset the CEL for you and it still hasn't come back on, it could have just been a one time occurrence and your actual air pump is fine. I've seen that happen many times as well.
Emulators aren't technically legal, but unless you're in a place like California that does an intense visual inspection of your engine bay I doubt an inspector would even look for it.
Anyhow, good luck with the car. cheers.

An emulator done correctly will 100% trick the cars computer which will trick the inspection station computer
Small world indeed--I'm over in Greensboro now. Lived in Raleigh/Cary for about 6 or 7 years total. Miss it sometimes. Othertimes, not so much

Update: Drove the 530i for over 100 miles, CEL was still off, tried to reinspect, Mechanic said it was not ready, P0411 code still pending. Ugh. This morning, CEL came back on about 15 seconds after starting the cold engine.
Gonna attempt to remove secondary air sensor (hose is permanently clamped) to check it out. But kinda pessimistic about it. Regardless, like NCSU suggested, my mechanic offered to give me a waiver inspection that will be good for a year. May still try to find or build an emulator. So far, no luck for my particular model. Thanks all for your input! Helped a lot.

I have 2004 530i. Bought it used... First owner was apparently a Canadian, The car's displays are in kilometers, Celsius, etc. Not sure if that affects the parts on the car. Seems to be like other e60s.
