2022-2023 Audi e-tron GT HV Heater Service Action 82C9

Audi has released a dealer communication, identified as Service Action 82C9, concerning 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 May 10, 2024, provides updated work instructions for technicians to address potential issues with the HV heater system.

Understanding Service Action 82C9

Service actions, like 82C9, are proactive measures taken by manufacturers to address potential issues that may not rise to the level of a safety recall but are important for vehicle performance and customer satisfaction. This particular action focuses on the Electric Passenger Compartment High-Voltage (HV) Heater, a critical component for climate control in electric vehicles. The communication indicates that updates have been made to the work instructions for this service action.

Symptoms of the HV Heater Issue

Owners of affected 2022-2023 Audi e-tron GT and RS e-tron GT models may experience their electric passenger compartment high-voltage heater ceasing to function. This issue is more likely to occur if the heater is used frequently for prolonged periods on a high setting, or if the vehicle's battery is frequently charged in low ambient temperatures. Consequently, this problem with the Audi e-tron GT HV heater is more prevalent in regions experiencing consistently cold environmental conditions. It is important to note that the waste heat scavenging heat pump, which also contributes to cabin heating, remains operational even if the primary HV heater encounters an issue.

What This Means for Owners

A malfunctioning HV heater can significantly impact driver and passenger comfort, especially during colder weather. Beyond comfort, a non-functional heater can also affect the vehicle's ability to defrost windows, which is a safety concern. While the heat pump may still provide some warmth, the primary heating capacity would be compromised. Owners should be aware that this service action aims to prevent or resolve instances where the Audi e-tron GT HV heater stops working.

Dealer Communication and Updates

The Audi dealer communication for Service Action 82C9 is primarily directed at dealer personnel. It emphasizes the importance of all dealership staff involved in campaign-related responsibilities thoroughly reviewing the revised circulars published in ELSA and Service References in Elsa2Go. Dealers are instructed to discard any previously printed paper copies and ensure they are replaced with the most current version of the work instructions. This ensures that technicians have the most up-to-date procedures for diagnosing and repairing the HV heater system.

Owner Action

If you own a 2022-2023 Audi e-tron GT or RS e-tron GT and experience problems with your vehicle's heating system, particularly if the electric passenger compartment high-voltage heater is not working, you should contact your authorized Audi dealer. They will be able to determine if your vehicle is covered by Service Action 82C9 and perform the necessary inspections or repairs according to the updated work instructions. Addressing the Audi e-tron GT HV heater issue promptly will help restore full climate control functionality to your vehicle.
