Emissions Failure
I just had the spark plugs changed and had the battery disconnected.
Well I immediately failed a soon after OBD scan for the Texas state inspection.
My O2 sensor and heated 02 sensor both show as not ready.
I see a lot of info out there, but what is the necessary "drive cycles" to get it ready?

Does the car still have a stock exhaust?

I just drove around for about 70 miles on my older cars (not the E63) when resetting everything. Then it would show a reading for them. I did a mix of city and highway driving. Best of luck!

As people have stated above - drive the car for about 50 miles, combined drive cycle, make sure to include some highway driving.
For some cars also good to start / stop once or twice.
There is a real protocol that you can follow - but usually not worth the hassle.
