2022-2023 Audi e-tron DC Charging Aborted TSB

Audi has issued Technical Service Bulletin (TSB) 2079068/1 to address a specific issue affecting certain e-tron and Q8 e-tron models. This bulletin details instances where DC charging procedures are sporadically aborted, particularly when the vehicle's high-voltage battery charger is running software version 0088. The TSB provides a clear resolution through a software update.

Symptoms

Owners may observe the following symptoms if their vehicle is affected by this issue:

• The vehicle sporadically aborts the DC charging procedure.
• The LED on the charging socket lights up in white during the complaint.
• AC charging functions correctly without any issues.
• No warning messages appear in the instrument cluster.

This condition specifically applies to vehicles with software version number 0088 in diagnostic address 00C6, which corresponds to the High-voltage battery charger.

Diagnostic Addresses and Software Versions

While no traditional Diagnostic Trouble Codes (DTCs) are generated for this specific issue, the problem is directly linked to the software version of the high-voltage battery charger. The relevant diagnostic addresses and software information are:

• Diagnostic Address: 00C6 (High-voltage battery charger) or 8113 (charging unit for high-voltage battery).
• Affected Software Version: 0088.
• Target Software Version: 0093.

Diagnosis and Trigger Conditions

Diagnosing this issue primarily involves verifying the software version of the high-voltage battery charger. The complaint may be sporadic and not always reproducible during workshop visits. Technicians will confirm the presence of software version 0088 in diagnostic address 00C6 as a key indicator for this TSB.

Repair Procedure Summary

The root cause of the Audi e-tron DC charging aborted issue is a software fault within the high-voltage charging unit. Therefore, no parts replacement is necessary or recommended, as this could lead to recurring complaints. The repair involves a software update:

1. Identify Affected Software: Confirm the vehicle has software version 0088 in diagnostic address 00C6 or 8113.
2. Software Update: Update the software for the charging unit to the new target software version 0093.
3. SVM Code: Use SVM code C6A022 to perform the software update.
4. Customer Instruction: Advise the customer that if DC charging is aborted again, they should unplug the charging connector from the vehicle and restart the charging procedure.

This TSB replaces the previous Pending Service Solution (PSS) TSB 2075879, which also addressed the e-tron charging aborted for DC charging with SW88.

Required Parts and Software Versions

This repair is primarily a software update. The following software and hardware part numbers are relevant:

• Old Software Version: 0088
• New Software Version: 0093
• Old Hardware Part Number: 5QE.915.684.CM
• New Hardware Part Number: 5QE.915.684.DG
• Service Number: 9352

Owner Action

If you own a 2022-2023 Audi e-tron or e-tron Sportback and are experiencing your Audi e-tron DC charging aborted sporadically, especially with the charging socket LED lighting up white, you should contact your authorized Audi service center. Explain your symptoms and mention Technical Service Bulletin 2079068/1. The repair involves a software update, which is typically covered under warranty. If your vehicle is outside of warranty, this TSB is informational only, but the software solution remains the recommended fix.
