If you want to transport the CE 02, make sure that you have activated transport mode so that the anti-theft alarm (DWA) is not triggered by any strong movements/vibrations.
To activate transport mode:
Press the BMW button on your radio-operated key once and a second time within 30 seconds.
If the turn indicator lights up 3 times, the DWA is deactivated and transport mode is activated.
You can also remove the batteries for easier transport. This reduces the vehicle weight by approx. 26 kg. Here you can find out how to remove the batteries.
