The ESP control unit switches the ESP and ASR function passive, however ABS is fully operational.
However the ESP is always active during a brake application.
The ESP and ABS warning lamp (A1e41) in the instrument cluster (A1) lights up permanently when the ESP is switched passive
The ESP and ABS warning lamp is actuated by the ESP control unit via the CAN engine compartment and the instrument cluster (A1).
