2025 Audi A5/S5/Q5 Key Fob LED Not Flashing TSB

Audi has released Technical Service Bulletin (TSB) 2076136/1 to address customer inquiries regarding the remote control key's LED. Owners of certain 2025 Audi models, including the A5, S5, and Q5, might notice that the LED on their key fob does not flash when a button is pressed. This TSB clarifies that this behavior is not a malfunction but rather a normal operating characteristic of the vehicle's key system.

The TSB, dated November 26, 2024, provides important information for both technicians and owners, confirming that the perceived issue with the 2025 Audi A5 key LED is not a defect and requires no repair.

Symptoms

The primary symptom reported by customers is that the "LED in the key does not flash when a button is pressed." This observation can lead owners to believe their key fob is faulty or that its battery is drained.

Important Warnings for Owners

Audi has issued specific instructions to address this concern, emphasizing that no repair is necessary:

• Do not perform any repairs. Any attempts to repair this condition may be denied under warranty.
• This condition is normal. Customers should be informed that the non-flashing LED is an expected behavior.
• Not a fault. If the LED does not flash, this is not necessarily indicative of a faulty key or a drained key battery.
• Informational only. This TSB is for informational purposes and is not applicable to any Audi Warranty claims for repairs.

Technical Explanation

For Audi Q6 and subsequent models built on the Premium Platform Electric (PPE) and Premium Platform Combustion (PPC) architectures, the LED in the key fob is designed to flash only after successful communication with the vehicle has been established. This means that the 2025 Audi A5 key LED may not flash in several common scenarios:

• When a button is pressed while the key is outside the vehicle's range.
• When there is a temporary communication issue between the key and the vehicle.

This design choice ensures that the LED provides feedback only when a successful interaction with the vehicle has occurred. The Owner's Manual may also contain information regarding this behavior, though it might be presented differently.

What Owners Should Do

If you observe that your 2025 Audi A5 key LED does not flash when you press a button, no action is required. This is a normal function of your vehicle's remote control key. There is no need to visit a dealership for this specific concern, as it does not indicate a fault or require any repair. Dealers are instructed not to perform any service for this condition.
