So I'm trying to code headlight washers to my E46 Coupe.
The GM5.C04 Trace file contains several options for the Headlight washers (SRA). But since there are several options I'm not quite sure of if they should be activ or not
MIT_SRA_EIN_LENKSTOCK
SRA_MIT_WASCH_WISCH_SW
OHNE_SRA_0
OHNE_SRA_1

So to be sure I wanted to go the official route and add option 502 to my VO. Now I followed one of the guides out there but I have one problem. After adding 502 to the VO and selecting GM5 as the ECU, I don't have the job option "FA Write"? Whilst I do think I need the GM5 ECU since that one has all the Headlight washer options in the trace file?

Am I doing something wrong? Or would there be a point in coding a different ECU?

You must select AKMB & ALSZ. Then recode the whole car.

Add $502 to AKMB and ALSZ. Then recode the GM5 (I don't think there are any other modules that the headlamp washers depend on)

Thanks for the tips! I added $502 to both the AKMB and ALSZ and dit a "Process car" run. The GM5 is different after that but still no headlight washers :/
If I manually bypass the relay they do work, and the relay is connected to the right pin (#12 of connector X253)
So for some reason they aren't triggered yet.
These are the options in the GM5 that I think relate to the Headlight washers with the settings after "Process car":

ANZAHL_WASCHBET_ZUR_SRA
5
MIT_SRA_EIN_LENKSTOCK
nicht_aktiv
SRA_MIT_WASCH_WISCH_SW
nicht_aktiv
ANZAHL_SPRITZIMPULSE
2
DAUER_SPRITZIMPULSE
700ms
PAUSE_ZW_SPRITZIMPULSE
1300ms
OHNE_SRA_0
aktiv
OHNE_SRA_1
nicht_aktiv
SCHEINWERFERREINIGUNG
aktiv

Can anyone confirm these settings?

Yes, someone can, me :stickoutt
I left the car for what it was, tried it again an hour later and now everything worked. Apperantly just switching off the ignition for a couple of secs wasn't enough to process everything.
