2023-2024 Audi Thermostat Leak Update 19PP

Symptoms of a Thermostat Leak

Audi has identified that the oil seal inside the thermostat in certain 2023-2024 vehicles may suffer from wear or deformation. This condition can lead to leaks from the thermostat. While the communication does not specify exact dashboard warnings or direct owner-perceptible symptoms beyond the leak itself, any unusual fluid leaks from the engine area should be investigated. This issue affects various models, including the 2024 Audi Q7.

Diagnosis and Trigger Conditions

This issue, identified by Audi's UPDATE 19PP, affects a range of 2023-2024 Audi models, with approximately 3,328 vehicles identified in the U.S. and Canada. To determine if a specific vehicle is affected, dealers are instructed to check the Campaigns/Actions screen in ELSA (Electronic Service Information System) on the day of repair. They must also review daily campaign open inventory reports or OMD (Open Market Data) for affected vehicles in their inventory. This ensures that all eligible vehicles, including those potentially experiencing a 2024 Audi Q7 thermostat leak, are identified for the necessary repair.

Repair Procedure Summary

To resolve the thermostat leak issue, the actuator for engine temperature regulation must be replaced. This repair became available on November 21, 2024. For complete repair and claiming instructions, technicians are directed to consult ELSA and Service References in Elsa2Go. The Parts Department is also advised to refer to the UPDATE technical bulletin for all required materials. This procedure ensures the proper functioning of the engine temperature regulation system and prevents further leaks caused by the oil seal's wear or deformation.

Important Warnings for Owners and Dealers

Audi has issued several critical notifications regarding this update, emphasizing specific actions and limitations:

• No Consumer Notification: "Updates differ from recalls and service actions; consumers are notified in writing of recalls and service actions. Therefore, consistent with general policy governing Updates, customers will not be receiving letters about this action."
• Delivery Hold: "Affected vehicles in dealer inventory cannot be delivered to consumers until this Update is completed." Dealers are required to repair every affected inventory vehicle before delivery to consumers.
• Workshop Action: "Each vehicle coming into your workshop (for maintenance or any other service visit) that shows this Update code open in ELSA on the day of repair should have the work completed." This ensures that vehicles are updated during routine service.
• Dealer Responsibility: Dealers must ensure that every affected vehicle receives the update before delivery to consumers.
• Inventory Identification: To identify affected vehicles in inventory, dealers should run the "New and CPO Inventory Open Campaign/Action Listing" report from the OMD Web system.

Owner Action

If you own a 2023-2024 Audi A3, A4, A5, A6, Q3, Q5, Q7, or S3, and are concerned about a potential 2024 Audi Q7 thermostat leak or similar issue, you should contact your authorized Audi dealer. Since owners will not receive direct notification for this UPDATE 19PP, it is important to proactively inquire about the campaign and check if your vehicle is eligible for this repair. Your dealer can check your VIN against the ELSA system to confirm applicability and schedule the necessary service.
