2022-2023 Audi e-tron GT HV Heater Malfunction

Audi has released a dealer communication, identified as 82C9, addressing a potential issue with the electric passenger compartment high-voltage (HV) heater in certain 2022-2023 Audi e-tron GT and RS e-tron GT vehicles. This communication, dated October 25, 2023, outlines the conditions under which the HV heater may stop working and provides instructions for its repair.

Symptoms of the HV Heater Malfunction

Owners of affected vehicles may experience a complete loss of heating within the vehicle's interior. The primary symptom is that "If the HV heater stops working, the vehicle interior will no longer be heated." This issue with the Audi e-tron GT HV heater is more likely to manifest under specific conditions.

Diagnosis and Trigger Conditions

The malfunction of the electric passenger compartment high-voltage heater is not constant but is more likely to occur under certain circumstances. These include prolonged periods of using the heater on a high setting or when the vehicle battery is frequently charged in low ambient temperatures. Consequently, this problem is more prevalent in regions experiencing consistently cold environmental conditions. It's important to note that even if the HV heater malfunctions, the waste heat scavenging heat pump will continue to operate.

Repair Procedure Summary

Audi's dealer communication 82C9 specifies a repair procedure that became available on October 26, 2023. The process involves inspecting the existing Z189 high-voltage heater. If the inspection reveals a malfunction, the heater will be replaced. Technicians are instructed to refer to the ELSA system and the Service References tool in Elsa2Go for comprehensive repair and claiming instructions.

Required Parts

The primary component involved in this repair is the Z189 high-voltage heater. Audi has indicated that there will be no specific parts allocation for this repair. Instead, high-voltage heaters will be made available to dealerships as VIN-to-order parts, ensuring that the correct component is supplied for each specific vehicle requiring service.

Important Information for Owners

Audi has outlined several key points for this repair action. Dealerships are required to check their daily campaign open inventory report or OMD (Open Market Data) for affected vehicles currently in their inventory. Crucially, every affected inventory vehicle must be repaired before delivery to consumers.

The 82C9 repair will be launched in multiple waves, with vehicles assigned based on specific criteria (e.g., criteria 01, criteria 02, and so on). Owners are advised that repairs should be scheduled immediately upon notification. Audi plans to begin owner mailing regarding this issue in November 2023.

What Owners Should Do
