SEOCONTENT-START

AUDI DEALER COMMUNICATION Ensure all dealership personnel are aware of this notice so they are able to address customer questions. Contact Warranty if you require additional assistance. Direct press inquiries to Audi Public Relations. Audi Customer Protection 93T7_DLR_ADV Advance Notice – Safety Recall 93T7 / High Voltage Battery This notice is for:  Dealer Principal  General Manager  Sales Managers  Service Manager  Parts Manager  Service Advisor  Warranty Administrator  Technicians Date: September 07, 2023 Issue: Under certain circumstances, there is a possibility that over time liquid can intrude into the high voltage battery of certain vehicles. Over time, if a sufficient amount of conductive liquid accumulates in the battery, arcing can occur, which could increase the risk of a thermal event. Precautions: If liquid enters the battery, a drop in insulation resistance results. If the insulation resistance value drops below a defined threshold over time, a yellow warning message is displayed in the vehicle. If the insulation value continues to drop below a defined threshold over time, a red warning message is displayed in the vehicle. Customers experiencing this situation are advised to contact their authorized Audi dealer without delay for an appointment to have the vehicle diagnosed. As a reminder, the vehicle owner’s manual contains important information regarding the vehicle’s warning lights and messages. We encourage anyone who drives the vehicle to review the owner’s manual to become familiar with the types of vehicle indicators, warnings and messaging they may see. Repair: • REPAIR NOT YET AVAILABLE • Check daily campaign open inventory report or OMD for affected vehicles in inventory. • Audi is working to make a recall remedy available as soon as possible for the affected vehicles. Dealers and owners will be notified in writing once the recall remedy work can be performed.

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 23V-613 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Volkswagen Group of America, Inc. Submission Date : SEP 01, 2023 NHTSA Recall No. : 23V-613 Manufacturer Recall No. : 93T7 Manufacturer Information : Manufacturer Name : Volkswagen Group of America, Inc. Address : 3800 Hamlin Road Auburn Hills MI 48326 Company phone : 1-800-893-5298 Population : Number of potentially involved : 1,899 Estimated percentage with defect : 3 % Vehicle Information : Vehicle 1 : 2023-2023 AUDI RS E-TRON GT Vehicle Type : Body Style : Power Train : NR Descriptive Information : The recall population was determined by production records. The vehicle populations prior to the recalled vehicle production period did not have the Teroson sealant and thus are not subject to the failure mode of the recall population. Vehicle populations subsequent to the recalled vehicle production period have an enhanced Teroson sealant and thus are not subject to the failure mode as the recall population. RS E-TRON GT: 461 Production Dates : SEP 23, 2022 – AUG 28, 2023 VIN Range 1 : Begin : WAUBHBFW7P7900840 End : WAUBHBFW4P7903131 ✔ Not sequential Part 573 Safety Recall Report 23V-613 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Vehicle 2 : 2023-2023 AUDI E-TRON GT Vehicle Type : Body Style : Power Train : NR Descriptive Information : The recall population was determined by production records. The vehicle populations prior to the recalled vehicle production period did not have the Teroson sealant and thus are not subject to the failure mode of the recall population. Vehicle populations subsequent to the recalled vehicle production period have an enhanced Teroson sealant and thus are not subject to the failure mode as the recall population. E-TRON GT: 1438 Production Dates : SEP 26, 2022 – AUG 25, 2023 VIN Range 1 : Begin : WAUCJBFW0P7001682 End : WAUEJBFW8P7006931 ✔ Not sequential Description of Defect : Description of the Defect : Under certain circumstances there is a possibility that over time liquid can intrude into the high voltage battery of certain vehicles. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Over time, if a sufficient amount of conductive liquid accumulates in the battery, arcing can occur, which could increase the risk of a thermal event. Description of the Cause : Insufficiently robust sealant of the high voltage battery can lead to the defect condition. Identification of Any Warning that can Occur : If liquid enters the battery, a drop in insulation resistance results. If the insulation resistance value drops below a defined threshold over time, a yellow warning message is displayed in the vehicle. If the insulation value continues to drop below a defined threshold over time, a red warning message is displayed in the vehicle. Involved Components : Component Name 1 : High Voltage Battery Component Description : High Voltage Battery Component Part Number : 9J1.915.099.** / 9J1.915.100.** Part 573 Safety Recall Report 23V-613 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Supplier Identification : Component Manufacturer Name : DRÄXLMAIER Group Address : NR Vilsbiburg Foreign States 84137 Country : Germany Chronology : July 2022: Audi became aware of a potential issue involving reduced insulation resistance values which may indicate liquid intrusion into the battery. A detailed engineering investigation into the influencing factors and root cause was started together with the supplier. In September 2022, the HV battery supplier introduced a Teroson sealant into the battery production process in an effort to increase sealant robustness. Field monitoring continued. March 2023 – August 2023: Additional evaluations and testing were initiated based on reports of reduced insulation resistance values in vehicles with the Teroson sealant from non-US markets. Audi continued investigating the cause of the liquid intrusion and concluded that an improved and further enhanced Teroson sealant should be added to the HV battery. The enhanced Teroson sealant was implemented in May 2023 in the production process of the supplier. August 25, 2023: The results of the ongoing analysis were presented to the Audi Product Safety Committee. It was determined that there have been no reports of potential liquid intrusion in vehicles with the enhanced Teroson sealant that was implemented in May 2023. However, for the population built with the original Teroson sealant introduced by the supplier in September 2022 it cannot be ruled out that further cases of reduced insulation resistance values may occur in the field. Out of an abundance of caution the Audi Product Safety Committee decided a worldwide recall, based on the evaluation that, over time, if a sufficient amount of conductive liquid accumulates in the battery, arcing can occur which could increase the risk of a thermal event. Audi is not aware of any field reports in the US for HV batteries with the original Teroson sealant. Description of Remedy : Description of Remedy Program : Audi will conduct leak testing to detect the potential for leakage into the battery. If testing indicates the potential for leakage, the battery will be replaced. Audi will not offer a reimbursement plan under this recall because the vehicles affected would be covered under the new vehicle limited warranty. How Remedy Component Differs from Recalled Component : The remedy component includes an enhanced Teroson sealant. Identify How/When Recall Condition was Corrected in Production : The enhanced Teroson sealant was incorporated into battery production in May 2023.
