Emissions testing cycle?

[WTArmstrong]

Haven't contacted previous owner yet, he's on vacation (was leaving when I picked up the car last week, and I'm about 95% certain his location doesn't require emissions testing.

Codes... not irrelevant of course, but not *directly* tied to the emissions either. Again, it isn't FAILING emissions, just reporting that it is not ready. I cleared the codes last night in frustration (which reset the emissions readiness!), but mostly because I didn't know how old any of the codes might have been and was trying to get a clear baseline. Put about 60-70 miles on the car early this morning and so far none have come back. Emissions tests that report not ready are mostly centered around cat. converter, o2 sensor heating circuit, and evap. leak test. I'll go back down to the car in a bit and check.

Basically, any time the battery is disconnected, it resets the readiness test. I'm assuming the battery was disconnected during some of the prep work getting it ready to sell, I'm just trying to figure out what the cycle is that it wants me to complete. I found the one below online, but don't know that it is specifically for the E53, so trying to get as specific as I can since I'm not overly comfortable driving it around without plates.
