What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationBMW AG has issued a Delivery Stop (effective February 9, 2023) on certain Model Year 2022 – 2023 BMW vehicles that were produced between June 29, 2022 and February 16, 2023. This was originally called “Wireless Charging Tray”. Software in potentially affected vehicles may not recognize the removal of the digital key (Key Card or mobile phone) from the wireless charging tray, and thereby not meeting a federal requirement. On February 17, 2023 , the Delivery Stop was upgraded to a Non-Compliance Recall (see SI B84 01 23 ). SIB84 01 23 outlined a procedure for vehicles at that time which were- a) in BMW center inventory b) already delivered to customers This new SI B84 03 23 addresses vehicles which were in BMW center inventory or at the Vehicle Distribution Center (VDC) at that time. Those vehicles had the Key Card removed and were able to be retailed to the customer Such vehicles now need to return to the center to receive a new Key Card and updated programming. Please note that vehicles which were already in customer hands will be addressed by an update to SI B8401 23

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B840323 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 B840323 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 B840323 cover?
The manufacturer filed it against 23 model years: 2023 BMW 2 Series, 2022 BMW 2 Series, 2023 BMW 4 Series, 2022 BMW 4 Series, 2021 BMW 4 Series, 2023 BMW 8 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
