BMW bulletin B011423
BMW filed this with NHTSA as a service bulletin dated Nov 13, 2023, received Dec 6, 2023, about the engine and engine cooling. It names 84 model years (2016–2021). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B011423 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 B011423 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 B011423 cover?
The manufacturer filed it against 84 model years: 2021 BMW 2 Series, 2020 BMW 2 Series, 2019 BMW 2 Series, 2018 BMW 2 Series, 2017 BMW 2 Series, 2016 BMW 2 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
