What owners reported
Source: NHTSA complaint databaseOwners of the 237 model years this bulletin names have filed 3,719 complaints with NHTSA since 2015. 157 of them name Service Brakes — 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.
While parked in my residential garage with the engine shut off and car door closed, the vehicle suffered an un-commanded rollaway incident due to a suspected defect in the electronic parking brake or automatic-park transmission software. The vehicle was completely stopped, the driver exited the vehicle and the driver's door was closed.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi A4624592069078_2 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 A4624592069078_2 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 A4624592069078_2 cover?
The manufacturer filed it against 238 model years: 2025 Audi A3, 2024 Audi A3, 2023 Audi A3, 2022 Audi A3, 2020 Audi A3, 2019 Audi A3 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
