Diesel is oily, it's horrible stuff that can cause crashes if it's leaking onto the road in large enough quantities.
It's not like petrol that just evaporates.
HDi fuel filters are in the engine bay so it's not that.
It's usually the rubber elbow from the filler neck that fails and is only noticeable with a full tank. That's what my bet would be here.
