front washing system

Very sorry have not had time to check this out but give it a go and let us know

Control unit:
Module 09 - Electronic. Code (31347)
Function:
Adaptation
Value:
Select windshield wiper
Then Select SRA Verzoegerungszeit (SRA delay time)
Change value from default 0ms, I think the max is 2500

if its not this then it will be one of these hopefully

Number of activations front wash per SRA activation - Anzahl Betaetigungen Frontwaschanlage pro SRA Aktivierung:
This is by default set to 5 and means if you pull the washer lever 5 times it will activate the lights cleaning, so if you change this to 10 then it will clean your lights on the 10 pull (thus still working but using less water). I have tested this and it does work.

Delay Time - SRA Verzoegerungszeit: 0 ms

thanks to dj219957 here who says "So try changing  SRA Verzoegerungszeit to 2000ms and then you need to activate the screen wash for 2 seconds before the headlight washers will kick in."

washing time -  SRA Waschzeit:   500 ms

soaking break time -  SRA Einweichpausenzeit:  2000 ms
                     
                                SRA Nachwaschzeit:  500 ms

Break Time -  SRA Pausenzeit: 0 ms

If you want to turn the washer system off completely then do the following or use the app for 10 credits (tested and works on my car)

Select Byte 13
Select Bit 3 (description on OBD11 is Headlight Washers) and untick the box
