Volkswagen bulletin Bulletin 24IM

What it saysThe error detection of a stuck open secondary air valve is deficient above an altitude of 6560 ft. NHTSA’s full summary ↓

Volkswagen filed this with NHTSA as a service bulletin dated Oct 24, 2023, received Nov 6, 2023, about the engine. It names 1 model year (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.

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 database

Owners of the 1 model year this bulletin names have filed 120 complaints with NHTSA since 2015. 28 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.

While driving, the vehicle developed uneven acceleration and an audible metallic rattling/buzzing sound. Shortly after, the engine locked up, stalled, and jerked the car to a stop while in traffic.

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 579.5

Is Volkswagen Bulletin 24IM 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 Bulletin 24IM 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. Every Volkswagen warranty extension on file lists the ones Volkswagen has filed.

Which vehicles does Bulletin 24IM cover?

The manufacturer filed it against 1 model year: 2022 Volkswagen Golf / GTI. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
