2022-2025 Audi Q7/Q8 Third Row Seat Malfunction TSB

Symptoms of Third Row Seat Malfunction

Owners of 2022-2025 Audi Q7, SQ7, Q8, SQ8, and RS Q8 vehicles may experience a third row seat malfunction where the left or right backrest of the third row seats can no longer be folded up or down. This issue is often accompanied by a flashing warning lamp on the operating button, signaling a problem with the folding mechanism.

The problem can manifest in various ways, including the seat being too difficult to move, blocked, unable to be released, or having no function at all. The mechanism might feel stuck, unable to lock, or operate with an incorrect sequence. In some cases, the seat may only be partially out of order. This Audi Q7/Q8 third row seat malfunction directly impacts the utility of the vehicle's third-row seating.

Technical Background and Cause

According to Audi Technical Service Bulletin (TSB) 2079211/1, extensive analyses have determined that the third row seat malfunction is generally not a quality-related issue. Instead, the problem is attributed to external factors or objects. These external elements, such as items on the seat or in the luggage compartment, can block the folding mechanism, causing it to become jammed.

Important Warnings for Owners

It is crucial for owners to understand that this specific third row seat malfunction, as described in TSB 2079211/1, is not considered a manufacturing defect. Consequently, any work performed to resolve this issue, including labor and replacement parts, cannot be invoiced under warranty. Unjustified work or replacement parts will be charged back to the customer. Owners should be prepared for potential out-of-pocket expenses if their vehicle experiences this Audi Q7/Q8 third row seat malfunction.

Repair Procedure Summary

The repair procedure aims to eliminate the mechanical jam or blockage and restore the seat's original functionality. The process involves accessing the seat's control motors and manually cycling them to clear any obstructions.

1. Accessing the Mechanism: First, the luggage compartment floor must be removed to gain access to the relevant backrest connectors.
2. Left Backrest Repair: For a blocked left backrest, technicians will unplug the motor wire (white, 2-pin) and the control motor wire (red, 10-pin) on the left-hand side. They will then alternate applying 12V and ground (GND) to pins 1 and 2 of the motor's white connector to cycle the motor. Pin 1 with +12V and Pin 2 with GND folds the seat down, while Pin 2 with +12V and Pin 1 with GND folds it up. This process may need to be repeated several times to clear the blockage. Additionally, connecting pins 3 and 9 in the T10aax (red) connector with +12V and pins 4 and 10 with GND should help unlock the control motor and restore functionality.
3. Right Backrest Repair: For a blocked right backrest, the procedure is similar. Technicians will unplug the motor wire (black, 2-pin) and the control motor wire (black, 10-pin). They will then alternate applying 12V and GND to pins 1 and 2 of the motor's black connector. Pin 1 with +12V and Pin 2 with GND folds the seat down, and Pin 2 with +12V and Pin 1 with GND folds it up. This process may also require repetition. Finally, connecting pins 3 and 9 in the T10abx (black) connector with +12V and pins 4 and 10 with GND should unlock the control motor.

Owner Action

If you experience an Audi Q7/Q8 third row seat malfunction where your third-row seats are not folding or locking correctly, and you see the warning lamp flashing, it is recommended to contact your authorized Audi service center. Be aware that this repair is not covered under warranty, as it is considered to be caused by external factors rather than a manufacturing defect. Discuss the diagnostic and repair costs with your service advisor before proceeding with any work.
