What owners reported
Source: NHTSA complaint databaseOwners of the 9 model years this bulletin names have filed 21 complaints with NHTSA since 2015. 8 of them name Electrical 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.
The contact owns a 2026 Audi A6. The contact stated that while driving in stop-and-go traffic, a second vehicle reversed and struck the front end of the contact's vehicle. During the crash, the driver's side front air bag failed to deploy. The contact sustained a neck injury that required medical treatment.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2083831_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_2083831_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.
Which vehicles does TSB_2083831_1 cover?
The manufacturer filed it against 9 model years: 2026 Audi A5, 2026 Audi A6, 2027 Audi A6 e-tron, 2026 Audi Q5, 2027 Audi Q6 e-tron, 2026 Audi S5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
