What's wrong?
The Digital Key ECU software on affected 2022-2023 BMW Z4, M850I, 840I, 230I, M240I, M8, M2, and Alpina B8 vehicles controls how the car responds when a digital key is present or removed. The ECU is the electronic control unit, the computer that tells related systems when certain functions are allowed. In this recall, that includes the power windows and sunroof.
The problem is in the software coding. After the digital key is removed from the vehicle, the software does not correctly recognize that change in every operating condition. As a result, the power windows and sunroof remain able to close when they should be disabled under the federal power-window safety rule.
The owner is not given a separate warning sign that the software has misread the digital key. BMW says the vehicles have an auto-reversal and anti-trap function, which is designed to help reduce injury risk if something is caught while the glass is closing.

What's the safety risk?
A window or sunroof that closes without the key present can injure occupants inside the vehicle. Keep hands, arms, and children clear of the glass, even with the anti trap function active, and schedule the ECU software update. Repair is free at any franchised BMW dealer.
What should I do?
- Check your VIN to confirm your 2022-2023 BMW Z4, M850I, 840I, 230I, M240I, M8, M2, or Alpina B8 vehicle is included in this recall.
- Contact a franchised BMW dealer to schedule the free ECU software update that stops the digital-key condition from allowing the windows or sunroof to close after the key is removed.
- Bring the recall notice if BMW mailed one, and reference recall number 23V099 when you call.
- Avoid using the digital key function by cellular service or Wi-Fi until the BMW software update is complete.
- Keep occupants clear of the windows and sunroof when closing them before the repair is complete.
What happens at the repair
At the dealer, a BMW technician updates the Electronic Control Unit software so the digital key no longer allows the power windows or sunroof to close after the key is removed from the vehicle. BMW also deactivates the digital key function through cellular service and Wi-Fi capability until the vehicle receives the new software. Parts and labor are covered under the recall. BMW used its standard reimbursement plan for this campaign, so owners who already paid for a related repair should bring documentation and ask the service desk how to submit it.
