What it saysThis bulletin provides information when there is a squeaking noise from the front of the vehicle while driving. NHTSA’s full summary ↓
Audi filed this with NHTSA as a service bulletin dated Feb 15, 2024, received Mar 6, 2024, about the suspension. It names 27 model years (2017–2022). 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.

Read by machine from the document NHTSA serves (4 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 27 model years this bulletin names have filed 1,046 complaints with NHTSA since 2015. 302 of them name Engine, 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.
We are told by Audi dealer service that our entire water pump system is defective and needs to be replaced at a cost of $5000+. We've had Audis subject to past recall and class action settlements. This is an ongoing, known issue for Audi for over a decade. Frustratingly, our 2020 SQ7 model is not included in any current recalls.

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.

Throttle lag from a near (but not full) stop. If coming to rolling stop, from 1-8 MPH, and then hit accelerator, the car engine revs but no acceleration to vehicle. After a 2-3 second delay, car will lunge and accelerate normally. Scary when need to accelerate from a near rolling stop. Left hand turns especially dangerous.

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 A4024742058489_8 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 A4024742058489_8 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.
