Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Audi’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

On March 22, 2026, my Check Engine light came on while driving my 2022 Audi A3. Prior to this, I had been noticing a slight jerk when accelerating from a stop. Because Audi dealerships charge approximately $250 just to read diagnostic codes, I went to Discount Auto Parts, where they retrieved code P27F500 — indicating the gear shift lock…

2021 Audi e-tron, 44,749 miles. Right after a scheduled service at Audi on XXX, I noticed a loud droning/humming noise from the drivetrain while driving. The noise tracks with vehicle speed - it gets louder and higher-pitched as the car goes faster. I called the dealership to report it as soon as I got the car back in late XXX.

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 A4025862061464_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 A4025862061464_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.
