What's this wire

I was ripping out some redundant wiring at the weekend, resolving years of add-ons that no longer work and found this wire just behind the fuse/relay panel, not connected to anything, never got a chance to check if it was live or not.
Does anyone have any idea what it is normally used for?
Grey/Yellow
Thanks all.

In the late years VW started to use common wiring harnesses on vans with different trim/accessory levels.
Grey/yellow if connected to B connector pos 20 then it is relayed power feed to the fog light switch

Makes sense, thanks for the info.
