Defect Code 21:

*D* Defect code memory: Under voltage:

Note: This information does not refer to a defect in the area of the central locking system but rather it indicates that the voltage in the vehicle has dropped to below 8 V.

If this message occurs several times, it is displayed on the screen by the following overlay:

The cause should be examined in this case.
