2021-2022 Audi e-tron Pressure & Temperature Sensor Service Action

Understanding Service Action 87H9 for Audi e-tron Pressure Temperature Sensors

Audi has issued a dealer communication, identified as Service Action 87H9, concerning the pressure and temperature sensors in the air conditioning system of certain 2021-2022 Audi e-tron vehicles. This communication, dated February 23, 2024, informs dealers about updated claiming instructions related to this service action. Owners searching for information about their Audi e-tron pressure temperature sensors should be aware of this action.

The Issue: Air Conditioning Sensor Failure

The core issue addressed by Service Action 87H9 involves the pressure and temperature sensors within the air conditioning system. These sensors are critical components that monitor the refrigerant pressure and temperature, providing essential data to the vehicle's climate control module. If these sensors fail, the air conditioning system in the affected 2021-2022 Audi e-tron vehicles may cease to function correctly. This can manifest as a complete loss of cooling or heating, inconsistent temperature control, or the inability to activate the AC system at all. Such a malfunction directly impacts occupant comfort and can also impair the effectiveness of defrosting or defogging functions, which are crucial for visibility and safety.

What This Revision Means for Service Action 87H9

This particular dealer communication (NHTSA ID 10250818) is a revision to the existing Service Action 87H9. It specifically updates the "claiming instructions" for dealers. Claiming instructions are the detailed guidelines that dictate how authorized Audi dealerships submit warranty claims to Audi for reimbursement when performing repairs or service actions. This ensures that dealers can correctly process the necessary paperwork and receive proper compensation for the labor and parts involved in addressing the Audi e-tron pressure temperature sensors issue.

For owners, this update primarily affects the administrative side of the repair process. It doesn't change the underlying technical procedure for fixing the problem, but it ensures that dealers are properly guided on how to handle the service action under warranty. This administrative clarity helps streamline the repair process for customers and ensures that dealerships are properly compensated for their work.

Important Information for Owners

While this communication is directed at dealer personnel, it's important for owners of 2021-2022 Audi e-tron vehicles to be aware of Service Action 87H9. If you experience issues with your air conditioning system, particularly a complete loss of function or erratic behavior, it could be related to the pressure and temperature sensors.

Audi advises all dealer personnel to thoroughly review the revised circular published in ELSA and Service References in Elsa2Go to ensure they are up-to-date on the correct procedures and claiming processes. Dealers are also instructed to discard any outdated paper copies of the circular and replace them with the most current version. This ensures consistency and accuracy across all service centers.

Next Steps for Owners

If you own a 2021 or 2022 Audi e-tron and are experiencing problems with your air conditioning system, or if you want to confirm if your specific vehicle is covered by Service Action 87H9, it is recommended to contact your authorized Audi dealership. Provide them with your vehicle's VIN and specifically mention Service Action 87H9. They can check the specific details for your vehicle and schedule any necessary inspections or repairs related to the Audi e-tron pressure temperature sensors.

This type of service action is typically performed at no cost to the owner if the vehicle is within the warranty period or if the service action itself specifies it as a free repair. Always confirm warranty coverage and potential costs with your dealership before any work is performed.
