I happened to be cleaning the cab of the van today and noticed something had been leaking behind the trim on the passenger side. My first thoughts were maybe something had leaked in the glovebox but I'm the only one to drive it and I know there hasn't been anything in there. Its definitely oil-like but was clear so I'm thinking its likely to be diesel rather than engine oil. Its not bad, I wiped it to see what it was before taking the photos but I don't think its much of a leak, may have been a one-off incident. Anyone got any ideas?
