Bulletin History and Revisions

This Technical Service Bulletin, identified as 00 23 69 2031473/4 and issued on May 8, 2023, addresses the issue of car wash bristles. It supersedes an earlier bulletin, Group 00 number 21-47, which was dated June 23, 2021. The bulletin itself has undergone several revisions to update its header with additional models and model years:

• Revision 4 (May 8, 2023): Revised header to include additional models and model years.

Symptoms

Owners typically discover this issue when they observe "Bristles from the car wash are discovered between the headlight and the front fender". This condition is usually noticed after the vehicle has been washed in an automatic car wash. Figure 1 in the original bulletin visually illustrates a "Car wash bristle is stuck in the body gap" between the headlight and fender.

Technical Background

The design of various Audi models, spanning from 2011 to 2024, includes a specific gap in the area around the headlights. This design feature can unfortunately allow bristles from certain types of car washes to become trapped. When a vehicle is washed in an automatic car wash utilizing particular bristle angles and types, these bristles can tear away from the car wash mechanism and lodge themselves firmly in the gap between the headlight assembly and the front fender. This explains why an owner might find Audi e-tron car wash bristles or similar debris on other Audi models.

Service Procedure

If you encounter Audi e-tron car wash bristles or bristles on any other affected Audi model stuck in the headlight seam, the recommended service procedure is straightforward:

1. Remove Bristle Fragments: Carefully remove all visible bristle fragments from the affected area around the headlight.
2. Explain Cause to Customer: Technicians are instructed to explain to the customer that the issue is a result of the vehicle's design and the specific type of car wash used.
3. Suggest Alternative Car Wash: Advise the customer to consider using a different type of car wash to prevent future occurrences of bristles becoming trapped.

Important Warranty Information

It is crucial for owners to understand that this issue, whether it involves Audi e-tron car wash bristles or any other Audi model, is classified as damage resulting from outside influence. Consequently, this type of damage is not covered by any Audi Warranty. Owners will be responsible for the cost of removing any trapped bristles.

Additional Technical Notes

For technicians performing this service, it is important to note that all part and service references within this TSB (specifically referencing 2031473) are subject to change. Technicians should always consult their Parts Department and/or ETKA for the most current information and parts bulletins. Additionally, the Repair Manual should be referenced for details on fasteners, bolts, nuts, and screws that may require replacement during any related repair.

Owner Action

If you discover car wash bristles trapped in the headlight-fender seam of your 2023-2024 Audi, you should:

• Visually inspect the area around your headlights after using automatic car washes, especially if you suspect the car wash uses stiff bristles.
• Contact an authorized Audi service center to have the bristles professionally removed. Attempting to remove them yourself might inadvertently cause damage.
• Discuss the type of car wash you use with your service advisor. They can provide guidance on alternative car wash options that are less likely to cause this issue, helping to prevent future instances of Audi e-tron car wash bristles or similar problems.
