Limp-home mode, general 

In order to guarantee a safe driving condition and to avoid damage to the automatic transmission, the fully integrated transmission control unit (N15/15n4) switches to limp-home mode in the event of critical faults.

In the case of solenoid faults, the affected gear is blocked and no longer actuated.

The driver can therefore drive the vehicle to the nearest Mercedes-Benz service operation.
