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 11 model years this bulletin names have filed 43 complaints with NHTSA since 2015. 11 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.
Excessive Engine Oil Consumption. Audi Corp is attempting to rebuild the engine vs replacement leading to increased customer risk and downtime. My SQ8 has been in the shop for 250 days due to serval rebuild attempts with the dealer requesting a new engine and Audi denying forcing the rebuild even after several failed attempts.
2022 Audi SQ8 · Engine · filed with NHTSA Feb 10, 2026 · ODI 11717057
About a year ago, right after the warranty period was over, the water pump and related had to be replaced and car would not run right. This water pump is a well known issue with audi and had a recall already. My car was the year after but it happens to almost everyone at around 50-55k miles.
2022 Audi SQ8 · Engine · filed with NHTSA May 6, 2026 · ODI 11736200
The car started over heating at 39,000 miles with the warning that “coolant temperature too high, let engine run with vehicle stationary.” Took it to the dealer for repairs and they said it’s a bad thermostat and water pump which requires the entire front end to be disassembled to change.

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_2065684_6 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_2065684_6 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_2065684_6 cover?
The manufacturer filed it against 11 model years: 2021 Audi A8, 2022 Audi RS, 2021 Audi RS, 2022 Audi RS Q8, 2021 Audi RS Q8, 2022 Audi S8 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
