The customer complaint specifically states: "The preferred charging time function cannot be set."

Fault Codes / Diagnostic Addresses

Upon workshop diagnosis, the complaint can be reproduced. Technicians will find that the vehicle has software version number 1191 in diagnostic address 00C6, which corresponds to the High-voltage battery charger (J1050).

Repair Procedure Summary

To resolve the issue where the Audi preferred charging time cannot be set, Audi dealerships will perform a software update on the High-voltage battery charger (J1050). The procedure, outlined in TSB 2073891/1, requires the use of a VAS tester equipped with the current version of ODIS diagnostic software.

Here's a summary of the steps:

1. Prepare Diagnostic Equipment: Ensure the VAS tester has the latest ODIS version. Technicians must activate DoIP (Diagnostic 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 tool indicates that DoIP is active.
2. Follow SVM Instructions: Refer to TSB 2011732, which provides detailed instructions for Software Version Management (SVM) operating procedures.
3. Update Software: Update the High-voltage battery charger (J1050) using the SVM action code C6A013. This process will update the software from version 1191 to the improved software version 1192. The update will also change the part number for the software. For example, old software part numbers like 5QE.915.681.DB and 5QE.915.681.DD will be updated to 5QE.915.681.EB and 5QE.915.681.EA respectively, while 5QE.915.681.DC will update to 5QE.915.681.EC.

Important Warnings

Technicians are advised that the DoIP communication setting will automatically reset once the diagnostic session has ended. It is crucial to always use DoIP when flashing a control module via ODIS in supported vehicles.
