What the bulletin says
Source: NHTSA's summary of the manufacturer's communication"AIRBAG WARNING LIGHT: ACSM FC 930A60 OR 930A1C SEAT OCCUPANCY DETECTION. According to the customer, the airbag warning light was on, but it may not be on when the vehicle arrives in the workshop. 1. ACSM fault code ""930A60 - Seat occupancy detection, front passenger; malfunction"" is stored. The fault may or may not currently be present. Or 2. ACSM fault code ""930A1C - Front passenger seat occupancy detection transmitting fault (moisture)"" is stored. The fault may or may not currently be present. The front passenger seat occupancy mat consists of a seat occupancy mat with a capacitive sensor system. This means a front passenger is detected by measuring the resistance of the human body. The fault is set when moisture is detected on the mat itself."

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B650414 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 B650414 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 B650414 cover?
The manufacturer filed it against 67 model years: 2020 BMW 3 Series, 2019 BMW 3 Series, 2018 BMW 3 Series, 2017 BMW 3 Series, 2016 BMW 3 Series, 2020 BMW 4 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
