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 28 model years this bulletin names have filed 392 complaints with NHTSA since 2015. 5 of them name 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.
Our gas tank fuel level sensor is faulty so we can no longer tell how much gas is in our car. The check engine and fuel light are permanently on. This fuel sensor malfunction caused me to run out of gas in the middle of the road. The only way to fix it is to replace the entire gas tank at great expense. We were quoted $3500-$4000.

2019 Audi A4 · Fuel/Propulsion System · filed with NHTSA Dec 3, 2025 · ODI 11702724
Fuel gauge does not move at all and showed tank was 5/8 full. However, when I was on the freeway, the vehicle stalled because I was out of gas. Luckily, I was on the right lane and therefore was able to pull over to the side without an incident. This is a new vehicle with faulty fuel sensors.
2023 Audi S5 · Fuel/Propulsion System · filed with NHTSA Jan 7, 2023 · ODI 11500623
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 TSB_2079903_1 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 TSB_2079903_1 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.
