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).
