Would I be able to pass CO emission tests with 2 O2 codes related to my piggie pipes?

why'd you have O2 codes for piggies though, that shouldn't happen.
They used to use an OBD scanner to check the readiness, but it's been a while. Basically, when you clear the CEL, it resets the readiness codes. Takes 50 miles or so of driving to get them to adapt.

Hmmm. Everytime I clear them, they usually come back in 50 miles.
I'm not a VAG guru, but is there something I'm supposed to do to keep them cleared? They shop relocated the 02s, but I've had this CEL ever since then. I have some small pin holes in the welds where I can see exhaust is getting out, and I tried swapping the sensors around too. Thanks for the insight!

You are correct. It is an advisory item.
