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 164 model years this bulletin names have filed 2,935 complaints with NHTSA since 2015. 570 of them name Engine — 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 A2723602067906_3 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 A2723602067906_3 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 A2723602067906_3 cover?
The manufacturer filed it against 167 model years: 2024 Audi A3, 2023 Audi A3, 2022 Audi A3, 2020 Audi A3, 2018 Audi A3, 2017 Audi A3 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
