2022-2023 Audi e-tron DC Charging Aborted TSB 93 PSS

Symptoms of Sporadic DC Charging Abortions

Owners of 2022-2023 Audi e-tron and e-tron Sportback vehicles may experience their vehicle sporadically aborting the DC charging procedure. This interruption means the charging process stops unexpectedly. When this Audi e-tron charging aborted event occurs, a key indicator is that the LED on the charging socket will light up in white, signaling an issue with the connection or process.

Technical Background and Diagnosis

Technical Service Bulletin 93 PSS 2075879/1 explains that this condition occurs in particularly rare cases and is linked to the onboard charger software version 0088. This specific software version can be identified in diagnostic address 00C6 within the vehicle's systems. The TSB applies under specific diagnostic conditions:

• AC charging functions normally without any problems.
• There are "no warning message appears in the instrument cluster" related to charging issues.
• The LED on the charging socket illuminates white when the DC charging abortion occurs.
• The vehicle's onboard charger has software version number 0088 in diagnostic address 00C6.

Workshop technicians may find that the complaint cannot always be reproduced during diagnostic testing due to its sporadic nature, making consistent diagnosis challenging.

Important Warnings for Owners

Audi has issued critical guidance for owners and technicians regarding this specific issue:

• Do not replace any components for this condition. Replacing parts will not resolve the sporadic DC charging abortion issue. The TSB explicitly states that such replacements are ineffective and will not address the customer's concern.
• If you experience the issue where "DC charging may sporadically be aborted" again, the DC charging connector must be unplugged from the vehicle and the charging procedure must be restarted. This is the recommended immediate action for owners to resume charging.

This solution is currently under development, and the bulletin will be updated once more information becomes available. A fix is expected to be available by the end of the first quarter of 2025, though this timeline is subject to change. At this point, no repairs are necessary for this condition.
