Audi bulletin A4023672047920_7
What it saysThis bulletin provides information when there are noises from the front end and dash panel when the vehicle is moving. NHTSA’s full summary ↓
Audi filed this with NHTSA as a service bulletin dated Aug 8, 2023, received Sep 1, 2023, about the engine. It names 132 model years (2020–2026). 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 owners reported
Source: NHTSA complaint databaseOwners of the 131 model years this bulletin names have filed 1,401 complaints with NHTSA since 2015. 211 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 A4023672047920_7 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 A4023672047920_7 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 A4023672047920_7 cover?
The manufacturer filed it against 132 model years: 2024 Audi A3, 2023 Audi A3, 2022 Audi A3, 2020 Audi A3, 2024 Audi A4, 2023 Audi A4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
