Service bulletin Dealer 23Z8
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Audi is releasing a software calibration update to the Approved Emissions Modification (AEM) to improve on-board diagnostics (OBD) monitoring of vehicle emissions systems and provide other improvements to the software used by the vehicle. Additionally, to reduce soot accumulation affecting the oxygen sensor, it is necessary to replace and relocate the sensor, which requires replacement of the diesel oxidation catalyst (DOC) and diesel particulate filter (DPF).
