2025 Audi A5/Q5 Windscreen Noise TSB 2078650/1

Symptoms

Owners of certain 2025 Audi models may experience a noticeable noise from windscreen/dash panel area when driving, particularly on uneven roads. This noise often seems to originate from the dash panel. However, if you shift your head closer to the steering wheel, the sound can be more clearly identified as coming from the upper part of the windscreen. This specific 2025 Audi A5 windscreen noise can manifest as general noises or vibrations.

Diagnosis / Trigger Conditions

Audi workshops have identified that the root cause of this noise is the left and right windscreen pins. These pins, initially installed during vehicle assembly, can move relative to the vehicle body, leading to the audible disturbances reported by customers.

Technical Background

The windscreen pins play a crucial role during the manufacturing process. They are used to secure the windscreen in place while it is being bonded to the vehicle body, preventing it from slipping during this critical stage. Once the bonding process is complete and the adhesive has cured, these pins are no longer functionally required. However, if they remain in place and are not properly secured or removed, their movement can generate the 2025 Audi A5 windscreen noise that owners experience.

Audi has a production solution planned for approximately week 25 of 2025. This solution involves implementing a new 2-component windscreen pin design that features softer plastic in the area that contacts the vehicle body. This change aims to prevent the movement and subsequent noise from occurring in future production vehicles.

Repair Procedure Summary

To address the noise from windscreen/dash panel area identified in TSB 2078650/1, a specific repair procedure is outlined for affected vehicles. The process involves several key steps:

1. Preparation: Technicians must first remove the A-pillar trim and both the left and right sun visors to gain access to the windscreen pin area.
2. Pin Securing: A 2x 2 cm piece of butyl adhesive sealing cord is then applied to the windscreen pin. This cord is carefully stuck onto the pin to prevent it from falling out or moving during the next step, which could otherwise lead to noise after the pin is removed.
3. Pin Removal: Using a narrow sharp screwdriver or a small chisel, the windscreen pin is carefully knocked out from its position. The TSB provides visual guidance for this step, showing the precise angle and tool usage.
4. Post-Removal: The bulletin specifies that the remains of the removed pin, along with the butyl adhesive sealing cord, can be left within the vehicle structure after removal, as they no longer pose a functional or noise issue.

Required Tools or Parts

Technicians will need the following items to perform this repair:

• 2x 2 cm butyl adhesive sealing cord
• A narrow sharp screwdriver or small chisel
