Audi filed this with NHTSA as a service bulletin dated Sep 8, 2025, received Oct 3, 2025. It names 72 model years (2020–2024).

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2076404_5 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 TSB_2076404_5 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 TSB_2076404_5 cover?
The manufacturer filed it against 72 model years: 2023 Audi A3, 2022 Audi A3, 2023 Audi A4, 2022 Audi A4, 2021 Audi A4, 2020 Audi A4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
