One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page.

I purchased a new 2024 Audi Q4 e-tron. The first malfunction occurred in January 2025 when a dashboard warning appeared stating the vehicle was “unable to read traffic or road signs.” The dealer confirmed a front-camera sensor failure and replaced the camera under Repair Order #193312 (1/17/25 – 1/29/25) at approximately 397 miles.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi AOS-24-84 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the AOS-24-84 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does AOS-24-84 cover?
The manufacturer filed it against 1 model year: 2024 Audi Q4 e-tron. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
