What it saysDAYTIME RUNNING LIGHT IS DIM OR DISCOLORED: This Service Information Bulletin (Revision 2) replaces SI B63 04 18 dated January 2019. NHTSA’s full summary ↓
BMW filed this with NHTSA as a service bulletin dated Jul 21, 2025, received Feb 25, 2019, about the exterior lighting — 8 documents under this number. It names 81 model years (2016–2024). 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.

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 61 model years this bulletin names have filed 2,301 complaints with NHTSA since 2015. 702 of them name Electrical System, Air Bags, Exterior Lighting — 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.
On the 2019 BMW X5, the 19 owners who gave an odometer reading for Electrical System reported it at a median of 55,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The first time the service department replaced the battery on my remote key control, the second time service told me it was a known problem at Bmw and they were working…

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 BMW B630418 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 B630418 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 B630418 cover?
The manufacturer filed it against 81 model years: 2024 BMW 2 Series, 2020 BMW 2 Series, 2024 BMW 5 Series, 2023 BMW 5 Series, 2022 BMW 5 Series, 2021 BMW 5 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
