Audi bulletin TSB_2083709_1
What it saysThis bulletin provides information when there is an Audi pre sense warning, warning jolt, or brake intervention. NHTSA’s full summary ↓
Audi filed this with NHTSA as a service bulletin dated Oct 19, 2026, received Nov 4, 2026, about the electrical system. It names 60 model years (2017–2025). 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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 60 model years this bulletin names have filed 1,849 complaints with NHTSA since 2015. 555 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.
On the 2018 Audi Q5, the 19 owners who gave an odometer reading for Electrical System reported it at a median of 48,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

My 2023 Audi SQ5 Sportback's key fob stopped working, and when I took it into the Audi dealership they said that it is a known issue that if you don't unclog the drain (not sure where that is - was never told I needed to do so) then there can be leaks that affect the wiring and the Comfort Control Module, rendering the vehicle unusable.

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_2083709_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_2083709_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_2083709_1 cover?
The manufacturer filed it against 60 model years: 2025 Audi A4, 2024 Audi A4, 2023 Audi A4, 2022 Audi A4, 2021 Audi A4, 2020 Audi A4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
