2022-2024 Audi e-tron GT High-Voltage Heater TSB 82NE

Audi has released Technical Service Bulletin (TSB) 82NE to address a specific issue affecting the high-voltage heater in certain 2022-2024 Audi e-tron GT and RS e-tron GT vehicles. This proactive update aims to prevent a condition where the high-voltage heater may fail, impacting the vehicle's heating capabilities.

The TSB, identified as 82NE, was originally published on August 1, 2025, and applies to 85 E-TRON GT and 33 RS E-TRON GT vehicles in the U.S. market. Owners of affected vehicles experiencing issues with their heating system should consult an authorized Audi dealer.

Symptoms

Owners of affected 2022-2024 Audi e-tron GT and RS e-tron GT vehicles may experience a noticeable lack of interior heating. This occurs because a quality issue can cause the high-voltage heater to automatically switch off in the event of a fault. The primary symptom is the vehicle "no longer heating the vehicle interior."

Diagnosis / Trigger Conditions

Diagnosis for this condition primarily involves verifying the vehicle's eligibility through the Audi ELSA system. Technicians must check the ELSA Campaign/Action Information screen for the presence of the "82NE code" on the day of repair. The status in ELSA must show as "open" for the procedure to be valid. If the code appears to have been performed but still shows open, the warranty department should be contacted.

Important Warnings

Audi emphasizes several critical warnings related to working with the high-voltage system:

• "Extremely dangerous due to high voltage." The high-voltage system carries severe voltage, posing a risk of electrocution or electric arcs. Only trained Audi high-voltage technicians or experts should de-energize the system.
• "The electric and magnetic fields are extremely dangerous." These fields can cause death or serious injury, especially to individuals with active implants like cardiac pacemakers or insulin pumps. Persons with active implants must not perform procedures on the high-voltage system.
• "Risk of injury - motor may start unexpectedly." It can be difficult to determine if the drive system of an electric or hybrid vehicle is active. Moving parts can cause injury.
• "Risk of damage to high-voltage wiring." Incorrect handling can damage the insulation of high-voltage wires or connectors. Technicians must not support themselves on high-voltage cables, use sharp tools, or perform welding/brazing near high-voltage components.
• "CRITICAL REPAIR STEP: STOP STOP! STOP" All campaigns and actions with an available repair must be performed in order of their Start date. The oldest should be performed first unless otherwise noted.
• This procedure is valid only for vehicles showing the "82NE code" in ELSA and must be performed within the New Vehicle Limited Warranty period.
• The procedure must be performed on applicable vehicles in dealer inventory prior to sale.
• Do not claim vehicle wash/loaner services under this action.
