2021-2023 Audi TFSIe Charging Time Cannot Be Set TSB

Symptoms

Owners of affected Audi TFSIe models may experience a specific problem with their vehicle's charging system. The primary symptom is that the "preferred charging time function cannot be set". This means drivers are unable to configure their vehicle to charge during specific time windows, which can impact convenience and energy cost management.

Technical Background

The root cause of the "preferred charging time cannot be set" issue is identified as a software fault within the high-voltage battery charger. Specifically, vehicles exhibiting this symptom are found to have software version number 1191 in address 00C6 (High-voltage battery charger, also known as J1050).

Diagnosis and Trigger Conditions

To diagnose this condition, a technician will reproduce the complaint and then check the software version of the high-voltage battery charger (control unit 00C6). If the software version is 1191, or an older version, and the preferred charging time function cannot be set, the vehicle is affected by this TSB.

Repair Procedure Summary

The repair involves updating the software of the High-voltage battery charger (J1050) to an improved version, 1192. This is performed using a VAS tester with the current version of ODIS diagnostic software.

The general procedure for resolving the "Audi TFSIe charging time" issue involves several steps:

1. Prepare Diagnostic Tool: Ensure the VAS tester has the latest ODIS software version.
2. Activate DoIP: The technician must activate DoIP (Diagnostics over Internet Protocol) communication. This is done by navigating to Administration >> General >> GFF Process >> DoIP communication >> Only allow DoIP communication within ODIS. A red LED on the VAS 6154(A) diagnostic interface indicates active DoIP.
3. Reference SVM Instructions: All instructions from TSB 2011732, titled "00 Software Version Management (SVM), operating instructions," must be followed.
4. Software Update: Update the High-voltage battery charger (J1050) using the SVM action code C6A013. The new software part numbers will vary by model but will be version 1192 or higher. For example, for the A7 TFSI e, the old software part number 5QE.915.681.DB (version 1191) is updated to 5QE.915.681.EB (version 1192).

Required Tools or Parts

To perform this software update, technicians will need:

• A VAS tester with the current version of ODIS diagnostic software.
• A VAS 6154(A) diagnostic interface, which supports DoIP communication.
• The improved software version 1192 for the High-voltage battery charger. Specific part numbers include 5QE.915.681.EC (for Q5 TFSI e), 5QE.915.681.EB (for A7 TFSI e), and 5QE.915.681.EA (for A8 TFSI e), replacing older versions like 5QE.915.681.DC, 5QE.915.681.DB, and 5QE.915.681.DD respectively.
