This bulletin applies to 2020 -2022 BMW vehicles. A Check Control message (CCM) may display a “Vehicle key missing” warning after the engine starts.
Several causes are possible when the key fob with a good battery is in the vehicle cabin:
- The key fob is not recognized due to unfavorable location in the vehicle interior
- Interference caused by radio antennas or high-voltage power lines
- Shielding of the key by metallic objects (mobile phone, wallet, etc.)
- Charging of mobile devices in the vehicle
- Charging of the high-voltage battery (battery electric vehicles or plug-in hybrid electric vehicles)
Program the vehicle using ISTA 4.31.1X or higher. Always connect a BMW-approved battery charger/power supply.
