Looks the same as a 2017-2020 shifter we have in North America. 2014 and 2015 models here only have d and b.
Anyways...I assume you’ll have to replace the shifter assembly. The transmissions are the same whether the have ds position or not. when shifted to ds position it doesn’t move the shifter cable and doesn’t move the switch on the transmission. It must hit a micro switch or something on the shifter inside the car. The schematic you posted above is irrelevant.
