2021-2023 Audi License Plate Mounting Bracket Stripped Inserts

Audi has issued Technical Service Bulletin (TSB) 66 21 69 2030471/6 to address a common problem where license plate mounting bracket threaded inserts become stripped. This TSB, dated February 9, 2021, supersedes an earlier bulletin, Group 66 number 18-64, from March 6, 2018, indicating ongoing attention to this issue. The primary concern is that the Audi license plate stripped inserts prevent proper installation of license plate screws.

Symptoms

Owners may notice that the license plate attachment screws do not install properly. This can manifest as screws spinning freely without tightening, or an inability to secure the license plate to the vehicle's bracket.

Technical Background

The license plate brackets are designed for installation using appropriate-length screws manually tightened with a screwdriver. The issue of Audi license plate stripped inserts often arises from applying excessive torque during installation or using screws that are too long for the specific bracket and license plate setup. This can cause damage to the internal threads of the mounting inserts.

Important Warnings

Audi explicitly advises: "Manually install the license plate screws using a handheld screwdriver. If the screw bottoms out, remove this screw and select a shorter screw instead of applying excessive torque. Otherwise, damage may occur to the license plate bracket screw inserts." It is crucial to follow this guidance to prevent damage. Furthermore, Audi states that "This damage is due to outside influence and is not covered by any Audi Warranty," meaning owners will likely bear the cost of repair if this issue occurs.

Repair Procedure Summary

To prevent or resolve Audi license plate stripped inserts, technicians and owners should pay close attention to the screw length and installation method. The appropriate screw length depends on the total thickness of the license plate and any decorative frame used.

• For a license plate without a decorative frame, an M6 x 8 mm screw is recommended.
• For a license plate with a 2 mm thick decorative frame, an M6 x 10 mm screw is recommended.

Always manually install license plate screws with a handheld screwdriver. If a screw reaches its limit and bottoms out, it should be replaced with a shorter screw rather than forcing it, which can strip the inserts. If the license plate bracket screw inserts are already damaged but the openings in the bracket remain intact, replacement inserts are available.

Required Parts and Tools

To address stripped inserts, the following part may be required:

• Part Number: WHT003200
• Part Description: Nut (M6)
• Quantity: 01-04 (as needed)

A handheld screwdriver is the only tool recommended for installation to ensure proper torque and prevent damage.

Owner Action

If you are experiencing issues with your license plate attachment screws not installing properly, it is important to inspect the license plate mounting bracket for stripped inserts. Given that this issue is typically not covered by warranty due to being classified as
