Audi filed this with NHTSA as a service bulletin dated Oct 1, 2023, received Nov 6, 2023, about the suspension. It names 61 model years (2018–2024). 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.

Read by machine from the document NHTSA serves (1 page), read Sep 30, 2026. A part number is shown only where it matches Audi’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 61 model years this bulletin names have filed 1,118 complaints with NHTSA since 2015. 855 of them name Electrical System, Engine, Fuel/Propulsion System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2020 Audi Q3, the 18 owners who gave an odometer reading for Engine reported it at a median of 2,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The first time, while driving at 50-55mph, the engine decelerated suddenly. After about 10-15 seconds struggles with the gas pedal and brake pedal, the car accelerated normally. I pulled safely to side of the road to shut off the engine and start again. Things seemed to work like normal. The control panels did not show any warning signs.

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 AVIN4PIN20231001 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 AVIN4PIN20231001 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 AVIN4PIN20231001 cover?
The manufacturer filed it against 61 model years: 2023 Audi A4, 2022 Audi A5, 2021 Audi A5, 2024 Audi A6, 2023 Audi A6, 2022 Audi A6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
