2024-2025 Audi A4 Remote Start Software Update TSB

Symptoms

Owners of 2024-2025 Audi A4 and A4 allroad models may experience problems with the remote engine start feature. The primary symptom reported is that the "Remote engine start via myAudi app does not work or only works intermittently." This can lead to inconvenience and frustration for vehicle owners relying on this functionality.

Diagnosis

When a customer reports that their Audi A4 remote start is not functioning correctly, technicians can confirm the condition in the workshop. The issue is typically reproducible, allowing for direct verification of the intermittent or non-functional remote start system.

Important Warnings

Audi has issued critical warnings regarding this software update, especially for vehicles with aftermarket modifications. Owners must be informed about the following:

• Chip Tuning: If the engine control unit has been altered by chip tuning, updating the software will render the chip tuning ineffective. In some cases, the engine control unit may even be damaged by the software update.
• Consult Tuning Company: Owners with chip-tuned vehicles should clarify with their tuning company whether a software update is possible before proceeding.
• Warranty Exclusion: Damage to the engine control unit resulting from chip tuning cannot be billed to AUDI AG under warranty.
• Responsibility for Damage: Neither AUDI AG nor the service facility can be held responsible for damage caused by the software update or for damage that occurs as a result of not having the update performed.

Technicians are instructed to make a note of these discussions on the repair order before it is signed by the customer and to include this information in the customer file.
