Ignition key data tapping on CBS vehicles

Situation:

In the interests of simplifying service reception the current vehicle data (e.g. CBS remaining values) are stored in the ignition key used last.

Note: The ignition key is overwritten with the current data during driving at specific intervals. As this writing process is repeated only after a defined distance, the key data may differ at service reception slightly from the most up-to-date vehicle data.

If a spare key with an out of date data status is handed over to the Service Advisor, it must be updated in the vehicle before service reception.

Procedure:

The process for writing the current vehicle data to the ignition key can be activated manually in the vehicle.

Data tapping in vehicles with key slot (E Series and MINI):

Sit in the vehicle and closed the door.

Note: Check the currency of the date and time settings in the vehicle.
