What owners reported
Source: NHTSA complaint databaseOwners of the 54 model years this bulletin names have filed 273 complaints with NHTSA since 2015. 3 of them name Suspension — 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.
During a recent inspection at Audi Chantilly (Virginia), the service department inspected cracked upper control arm bushings in the front suspension that were noted during a recent service to install new tires and perform an alignment (see attached photos. There is cracking and what appears to be some type of fluid leakage).

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_2073034_9 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_2073034_9 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_2073034_9 cover?
The manufacturer filed it against 54 model years: 2026 Audi A6, 2025 Audi A6, 2024 Audi A6, 2023 Audi A6, 2025 Audi A7, 2024 Audi A7 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
