corsa D rain auto light activation..

[sasa31]

Hello
I have corsa D 2012 model i want to retrofit rain/auto light sensor but when i plugged the all loom and parts i can not the pass the BCM it does not allow me to change this function..probably opel has locked that kind of modification after sales..how to fix this problem normally i had to see a menu "present or not present" but i even can not see this menu also..when i enter the rain sensor enabled section tech 2 says " it can not be modificated" how to pass this error..if i dump the bcm i can get pass through this error? i know maybe if i change the bcm i can fix problem or sps programming but it dosen t work also with opcom..
thanks..

Hello,
I know, that's while ago, but did you find it out? I have the same issue...
Thanks Josef

Bump !

Can you send me schematic of rain sensor ? I found something, but this is for pre-facelift. Was it different after face-lifting ?
