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.

What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 190 complaints with NHTSA since 2015. 130 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 MMI (Information and entertainment system) spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2065234_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 TSB_2065234_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.

The manufacturer filed it against 4 model years: 2021 Audi A4, 2020 Audi A4, 2021 Audi S4, 2020 Audi S4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
