He want's the "coming home/leaving home" function when locking/unlocking the car. So when you unlock it the dipped beam comes on and when you get out the car the dipped beam stays on for a short period after you lock it. Like on VAG models.
As mentioned above you have to manual activate this by pulling the left stalk towards you before exiting the car.
There is nothing to activate this when locking/unlocking in ELMconfig. I wish there was as I would like the same.
Don't suppose anyone has worked out how to wire this into work off the locking/unlocking system? Think it is something UCDS need to look into, as I am sure if could be done through the GEM if you have the ability to reprogram it.
