Interior light timing

[artag]

The interior lights come on when a door is opened but fade out in a few seconds. I think they're cancelled immediately if the engine is started or the doors relocked, but I'd like them to stay on for a few minutes if the doors are open - My older Picasso was longer though still a bit earlier than I'd have liked.

Is this something that's adjustable in the dealer diagnostics settings ? And if so, which of the several possible software packages do I need ?
