"Follow me home" function is broken

Hi,

I have a 9-5 Aero (2005, with Xenon headlights) as its first owner (I always loved and will ever love this car...). But I faced an extremely weird problem a few days ago.

I know "follow me home" function of the headlight and I used it frequently and enjoyed it at nights in front of the door of my house. So let me repeat again: I do know how to activate this feature. But now, it does not work and I do not know what could happen...

I have gone to the repair shop and the guy tested the DICE with his computer and told me that the configuration of the DICE is okay. Also, the normal light-functions work without any problem which means the cabling, relays and fuses have to be okay as well. So, I am completely at loss...

Does anyone have a solution or just any tip or idea?
This forum is my last hope...


Thanks in advance,
Attila
