A car pre 99 will pass with 2 non primary obd2 failures or up to 2 non primary not ready codes. Post 99 the limit is 1. A catalyst is primary so it will fail every time. I went through all of this with my M3 at my dad's garage. A lot of software will make the cat software Not Ready so the light doesn't come on but makes it so it fails inspection so cars aren't running around without catalytic converters

RAW, I had heard that as well, which is why I was hoping it would pass...but..
The result, she went yesterday and they just told her it would not pass because the cat was not ready, even though she had no CEL (which I was hoping she would pass with, so that way the cat doesnt need replacing) They didnt charge her or give her another R sticker, just told her that it wouldnt pass because of that.
The disease runs deep, relapses often, not looking for a cure, just another sick bastard to share it with.
