What it saysThe left charge air line can fail and cause an induction leak. NHTSA’s full summary ↓
MINI filed this with NHTSA as a service bulletin dated Sep 18, 2023, received Oct 1, 2023, about the engine. It names 4 model years (2024). 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
The left charge air line can fail and cause an induction leak. In some cases the “Engine Malfunction”warning may illuminate. Note: This Service Information is similar to M11 03 23; though this one pertains to vehicles already retailed.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches MINI’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.

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 4 model years this bulletin names have filed 5 complaints with NHTSA since 2015. 1 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.
The contact owns a 2024 Mini Cooper S. The contact stated that a brake pad failure message was illuminated on the vehicle. The vehicle was taken to the dealer, who diagnosed the brake fluid service issue. The brake fluid flush was completed, and a complimentary oil change was provided.

Common questions
Source: NHTSA, 49 CFR 579.5Is MINI M110423 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 M110423 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 BMW warranty extension on file lists the ones BMW has filed.
Which vehicles does M110423 cover?
The manufacturer filed it against 4 model years: 2024 MINI Clubman, 2024 MINI Cooper, 2024 MINI Countryman, 2024 MINI John Cooper Works. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: F54 MINI Clubman: built 13 Feb 2023 – 23 Jun 2023; F55 MINI Hardtop 4 Door: built 7 Feb 2023 – 29 Jun 2023; F56 MINI Hardtop 2 Door: built 9 Feb 2023 – 29 Jun 2023 — the build date is on the certification label in the driver’s door jamb.
