What shall we do to minimise the risk?
Theft using OBD
In 2012 BMW vehicles were stolen by programming a blank key fob to start the car through the on-board diagnostics (OBD) connection.The primary causes of this vulnerability lie in the lack of appropriate authentication and authorization in the OBD specifications, which rely largely on security through obscurity.
BMW is supposed to be offering a DME update to prevent this from happening. I would check with your service advisor if it's available yet.
