VCDS: Oxygen sensor failed or incomplete, Catalytic converter failed or incomplete

[overclocked]

Trying to get my emissions test on my just purchased used 2015A3 from an Audi dealer 2 days ago and get this:

Oxygen sensor failed or incomplete, Catalytic converter failed or incomplete

Repairpal research suggests it's a weak battery (battery last replaced back in 2017). Unless the car had been tuned by the previous owner that may be causing this? On my S6 I have APR downpipes with Stage 2, and have the o2 sensor workaround to pass emissions.

I do have a Audicare protection package just in case.

Thanks for any insights!

I would say...if there is no specific code for those in the engine fault codes...

the drive cycle didn't have enough time...to set readiness...incomplete.

Thanks. Yes no check engine light has come on. I did drive for over 150 miles. Maybe needs more highway miles.

Update: Put on another 75 miles and VCDS shows readiness has been set
