Audi bulletin SM C-2023
What it saysThis special notice is to inform dealers to return the parts listed only order the successor parts going forward. NHTSA’s full summary ↓
Audi filed this with NHTSA as a service bulletin dated Dec 20, 2023, received Jan 4, 2024, about the communication. It names 27 model years (2016–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 SM C-2023 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 SM C-2023 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 SM C-2023 cover?
The manufacturer filed it against 27 model years: 2023 Audi Q4 e-tron, 2022 Audi Q4 e-tron, 2023 Audi Q5, 2022 Audi Q5, 2021 Audi Q5, 2020 Audi Q5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
