2022-2024 Audi e-tron GT High-Voltage Battery TSB

Technical Background and Customer Complaints

Audi has issued Technical Service Bulletin (TSB) 2077772/2 to address customer complaints concerning the high-voltage battery assembly in certain e-tron GT and RS e-tron GT models. The primary workshop finding indicates that the high-voltage battery assembly must be replaced when these issues are identified. This TSB provides comprehensive guidance for technicians on the correct procedure and necessary components for this critical repair.

This bulletin is specifically relevant for 2022-2024 Audi e-tron GT and RS e-tron GT vehicles. The previous high-voltage battery assembly, identified by part number 9J1.915.100., is no longer available for new deliveries. Therefore, any replacement of the high-voltage battery assembly will require the updated part, 9J1.915.590., along with several other attachments and components detailed within this document. If your 2022 Audi RS e-tron GT high-voltage battery replacement is being performed, it will involve these updated parts and procedures.

TSB Information and Revisions

This Technical Service Bulletin, referenced as TSB 2077772/2, underwent revisions to ensure accuracy and completeness for technicians. The initial publication date for this TSB was May 5, 2025. It was subsequently revised on February 12, 2026. Revision 1, published on May 5, 2025, added a comprehensive model table to clarify the affected vehicles. Revision 2, dated February 12, 2026, further enhanced the document by including essential information regarding campaign handling, which is crucial for proper service execution and warranty claims. This ensures that all necessary steps are followed for a successful 2022 Audi RS e-tron GT high-voltage battery replacement.

Repair Procedure Summary

The replacement of the high-voltage battery assembly is a multi-step process that requires adherence to specific Audi workshop manual procedures and the use of precise parts. The overall process ensures the safe and effective installation of the new battery and associated components.

Ordering Parts and Removing the Faulty High-Voltage Battery

Technicians must begin by entering the vehicle's VIN number into the electronic parts catalogue. This step is crucial to ensure that the correct high-voltage battery and all necessary additional parts are ordered for the replacement. Once the parts are secured, the existing high-voltage battery must be carefully removed. This involves following the detailed instructions outlined in the workshop manual section titled "Electric drive motor 0EG, 0EM; Rep. gr. 93; High-voltage battery unit; Removing and installing high voltage battery unit 1 AX2." Additionally, the rear bracket, identified by part numbers 9J1.804.695/.696, needs to be removed and set aside for later use, as described in the workshop manual section "Electric drive motor 0EG, 0EM; Rep. gr. 93; High-voltage battery unit; Assembly overview – installed high-voltage battery." This initial phase is critical for safely disconnecting and extracting the old battery unit.

Converting and Installing the New High-Voltage Battery

Once the old battery is removed, the new high-voltage battery, part number 9J1.915.590.*, is prepared for installation. This involves placing the new battery onto a scissor-type lifting table, as depicted in Figure 2 (Label position location). This step is detailed in the workshop manual section "Electric drive motor 0EG, 0EM; Rep. gr. 93; High-voltage battery unit; Lifting high-voltage battery 1 AX2." Technicians then proceed to fit the necessary attachments for the front coolant connections, specifically parts 9J1.122.293.J (left side) and 9J1.122.293.K (right side), which are visible in Figure 1 (Overview of attachments).

Labeling Requirements

Accurate labeling is a crucial step in the replacement process. A notice, part number 9J1.01.003.B (E test mark), must be affixed next to the high-voltage battery type plate, as shown in Figure 2. Furthermore, a KBA-92109 label needs to be printed using a label printer and applied adjacent to the high-voltage battery type plate. The TSB notes that the KBA-92109 label is currently under development and will soon have an official part number. Until then, workshops are instructed to use a label printer or labeling machine to create a label with the text "KBA-92109" for application on the high-voltage battery next to the type plate.

Vehicle Changes and Component Replacement

To accommodate the new high-voltage battery and maintain vehicle integrity, several other components require replacement. Stabilizer links on both sides of the vehicle must be replaced to match the updated geometry of the e-tron GT PU (Power Unit). This involves replacing the left-side stabilizer link 9J1.413.357.A with 9J1.413.357.B, and the right-side stabilizer link 9J1.413.358.A with 9J1.413.358.B. These links are visually represented in Figure 3 (Stabilizer link). Technicians are also required to inspect all bolts, especially stretch bolts, and rubber bushes (shown in Figure 4) for any signs of wear and replace them if necessary. The procedure for replacing stabilizer links is found in the workshop manual section "Running gear, axles, steering; Rep. gr. 40; Subframe; Removing and installing subframe bracket." The process also includes renewing the reinforcement plate, replacing part number 9J1.407.129.F with 9J1.407.129.J, as illustrated in Figure 6 (Reinforcement plate). This is covered under "Running gear; Rep. gr. 40; Subframe; Assembly overview – Removing and installing subframe reinforcement."

Fitting Rear Brackets and Re-energizing the High-Voltage System

After the new high-voltage battery is installed, the rear brackets 9J1.804.695/.696 must be fitted to the high-voltage battery and torqued to specification, as shown in Figure 5. This is a critical step to ensure the battery is securely mounted. Following the physical installation of the new battery and associated components, the high-voltage system must be re-energized. This is performed according to the workshop manual's instructions up to the "Re-energizing high-voltage system" step. The re-energization process involves entry via "Flash" mode and utilizing the SVM (Authorized Multiple Code Entry) system. Specific SVM codes that must be entered are XCHG1HVBGTPA, XCHG2HVBGTPA, and DUCHISRES008CEGT. These codes ensure proper communication and functionality of the new high-voltage battery within the vehicle's electrical system.

Handling Open Field Campaigns

As part of the comprehensive repair, technicians are mandated to check for and process any open field campaigns related to the vehicle. If campaigns such as 931B, 931A, or 931D have not been marked as processed, they must be manually completed. Should any difficulties arise or further queries be needed regarding these campaigns, a ticket must be created within the WISH system for campaign coordination. This ensures all outstanding service actions are addressed during the 2022 Audi RS e-tron GT high-voltage battery replacement.
