Ok so I load revtor's profile, F1 --> F3 --> E53 --> EWS --> OK --> Back --> Process ECU --> LCM --> OK --> change jobs --> SG_CODIEREN --> Execute jobs (lights flash, says coding ended).
Do the same thing for GM3 module and RLS modules.

Then I do it one more time, choose LCM, change job to CODIERDATEN_LESSEN, open the FSW_PSW and it does say
LCM:
AUTOM_FAHRL_STEUERG
aktiv

I repeat this sequence for GM3 and open the file and see
WISCHERPOTI
nicht_aktiv

Did I miss something to make the wipers work when I spray water?
