Check Campaigns/Actions screen in Elsa on the day of repair to verify that a VIN qualifies for repair under this
action. Elsa is the only valid campaign inquiry & verification source.

Campaign status must show “open.”

If Elsa shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.
*The 82C9 repair will be launched in multiple waves. The first wave will be assigned
criteria 01, the second wave assigned criteria 02, and so on.
Problem Description
In the affected vehicles, the electric passenger compartment high-voltage heater may stop
working. This is more likely to occur if the heater is used frequently for prolonged periods on
high setting, or if the vehicle battery is frequently charged at low ambient temperatures. Thus,
this issue is more likely to occur in locations with frequently cold environmental conditions. The
waste heat scavenging heat pump remains operational.
If the HV heater stops working, the vehicle interior will no longer be heated.
Corrective Action
Code Visibility
Inspect and, if necessary, replace the high-voltage heater.
On or about October 26, 2023, the campaign code will be applied to affected vehicles.
Owner Notification
Owner notification will take place in waves, starting in November 2023. Owner letter examples
are included in this bulletin for your reference.
Campaign Expiration
Date
This campaign expires on December 01, 2028. Work must be performed on or before this date
to be eligible for payment. Keep this expiration date in mind when scheduling customers for this
action. If a customer wishes to have this work performed after the expiration date, your
dealerships normal costs associated with this work will apply.
Additional Information
Please alert everyone in your dealership about this action, including Sales, Service, Parts
and Accounting personnel. Contact Warranty if you have any questions.
Dealers must ensure that every affected inventory vehicle has this campaign completed before
delivery to consumers.

This notice applies to your vehicle:   , 
Subject: Service Action 82C9 - Electric Passenger Compartment High-Voltage (HV) Heater
Dear Audi Owner,
As part of Audi’s ongoing commitment to customer satisfaction, we are informing you of our decision to conduct a
service action on certain 2022-2023 model year Audi vehicles. Our records show that you are the owner of a vehicle
affected by this action.
What is the issue?
In the affected vehicles, the electric passenger compartment high-voltage heater may
stop working. This is more likely to occur if the heater is used frequently for prolonged
periods on high setting, or if the vehicle battery is frequently charged at low ambient
temperatures. Thus, this issue is more likely to occur in locations with frequently cold
environmental conditions. The waste heat scavenging heat pump remains operational.
If the HV heater stops working, the vehicle interior will no longer be heated.
What will we do?
Your authorized Audi dealer will inspect and, if necessary, replace the high voltage
heater. This work will take up to a day to complete and will be performed for you free of
charge. Please keep in mind that your dealer may need additional time for the
preparation of the work, as well as to accommodate their daily workshop schedule.
What should you do?
In order to limit any possible inconvenience, please contact your authorized Audi dealer
as soon as possible to schedule this work. Please keep in mind that your dealer may
need additional time for the preparation of the work, as well as to accommodate their
daily workshop schedule. For your convenience, you can also visit www.audiusa.com
and click on the “Find a Dealer” link to locate a dealer near you and schedule this
service.
This service action will be available for you free of charge only until December 01,
2028. If you wish to have this service performed after that date, your dealer’s normal
costs associated with this repair will apply.

Safety Precautions When Working ON the High-voltage System
(additional information is also available in the ELSA Repair Manual)
DANGER
Extremely dangerous due to high voltage.
•
The high-voltage system is under heavy voltage. Severe bodily injury or death by electrocution or electric
arcs is possible.
•
When working on the high-voltage system the high-voltage system must be de-energized.
•
When performing procedures that do not directly affect the high-voltage system, in some cases it is still
necessary to de-energize the high-voltage system.
•
Pay attention when the high-voltage system must be de-energized. Refer to the Repair Manual
•
Have a High-Voltage Technician or a High-Voltage Expert de-energize the high-voltage system.
The electric and magnetic fields are extremely dangerous.
•
There are electric and magnetic fields on the high-voltage system. Death or serious injury are possible due
to malfunction of active implants (for example cardiac pacemakers, insulin pumps).
•
Persons with active implants may not perform procedures on the high-voltage system.
WARNING
Risk of injury - motor may start unexpectedly
It is difficult to determine whether the drive system of an electric vehicle or hybrid vehicle is active. Moving parts can
trap or draw in parts of the body.
CAUTION
Risk of damage to high-voltage wiring
•
Incorrect handling may result in damage to the insulation of high-voltage wires or high-voltage connectors.
•
Do not support yourself on high-voltage cables or connectors.
•
Never prop tools against high-voltage wiring or high-voltage connectors.
•
Never bend or kink high-voltage wiring.
•
Observe the coding of the high-voltage connectors when joining them up.
Safety Precautions When Working NEAR the High-voltage System
(additional information is also available in the ELSA Repair Manual)
DANGER
Extremely dangerous due to high voltage.
•
The voltage levels in the high-voltage system constitute a safety hazard. Danger of severe or fatal injuries
from electric shock if high-voltage components or high-voltage wiring are damaged.
•
Carry out a visual check of high-voltage components and high-voltage wiring.
•
Never use cutting/forming tools or other sharp-edged implements.
•
Never perform work using welding, brazing, thermal bonding or hot air in the area of high-voltage
components and high-voltage cables.
