O2 sensor replacement, passenger side

[Devman2013S7]

Is this a DIY job for someone with minimal mechanic skills and a friend with decent skills helping out or do I need to take it into a shop? First time changing this out. 2016 RS7. Thanks in advance!

Passenger wheel into the air, remove the fender liner, remove the axle heat shield, disconnect connector, break zip tie if holding harness down and then use a normal O2 socket/breaker bar to crank it off like normal. Replace and do burn outs.

It took me no time to do mines, was able to get it from the top. Once you reach it, its just unscrewing the old one and putting in a new one

Passenger side is horrible. No visual line of light to the connector. Can't reach the connector without extreme contortions, and then can only get finger tips of one hand on it. It doesn't take a lot of mechanic skill, just patience.

The driver side for sure is easy, but the passenger side is not fun at all if you do it by the book. This is the first time I've heard of someone successfully pulling it off from the top, so if that's the case, we may have just saved ourselves some trouble in the future.

Ok changed out all 4 O2 sensors in the RS7, cleared codes but this morning 5 mins after a startup got these codes, any thought? Could it be Cats? Car is a 2016 with 99k miles.
