Airbag System Warning

• Airbag light on for DTC B12251B: If you own a 2022-2025 Audi Q7, an illuminated airbag warning light accompanied by DTC B12251B indicates a specific fault within the airbag system. This is a critical safety warning, and the Audi Q7 Airbag light B12251B should be addressed promptly.

Mechanical Noises

• Noise from engine belt tensioner: This issue affects 2024-2025 Audi A4, A5, Q5, and Q7 models. Owners might hear unusual noises emanating from the engine bay, specifically related to the belt tensioner.

Interior Component Malfunctions

Diagnosis and Repair Guidance

For each identified issue, Audi provides specific instructions for technicians:

• For oil leaks (timing chain cover gasket and oil filter): Technicians are instructed to take clear photos and videos of the active leak, including the oil filter o-ring, and then contact the Technical Assistance Center (TAC) with these visuals for further guidance.
• For ECM DTC P060600: If this fault is present, technicians should attempt to clear it. If the fault clears, a 20-mile test drive is required to confirm if the fault can be reproduced. Subsequently, TAC must be contacted for further instructions.
• For engine oil pressure switch issues: Technicians are directed to contact TAC for specific repair directions related to DTCs P055F00 and P055C00.
• For the Airbag light on for DTC B12251B: Technicians must contact TAC for further instruction before proceeding with any repairs.
• For noisy engine belt tensioners: Technicians need to verify the noise and then refer to TSB 2070568. They are also required to use a PICO tool to take basic acoustic measurements in the engine bay area and attach these readings to the TAC ticket.
• For dislocated steering column switches: Technicians should document the customer's complaint, take photos of the dislocated switch, and contact TAC for further direction. An onsite inspection (PQA) may be required.
• For binding sunroof shades: Technicians must inquire if the vehicle can be left at the dealer for an onsite inspection. If so, a TAC case should be created, and instructions awaited.
