Wading through fast moving water and knocking against some riverbed rocks seemed to damage my FL2 underbody.
Anyone knows what the exposed two cables are? A plastic or iron cover should be there for protection?

I am away from home otherwise would check my own to be sure, and await others to correct me for being wrong, but I think you will find these are the fuel feed and return pipes, which should be protected by a plastic cover. Freelander 2 XS 2.2 TD4 Met Black, with Winter pack, 18" alloys with General Grabber AT2 wellies, MANTEC Sump and Tank Guards

Its is the fuel lines,
This is what the workshop manual (via GTR) says.

"The fuel supply and return lines are routed along the vehicle underfloor, and housed within a plastic protection tray. The protection tray is secured with integral clips on the inside of the tray to studs along the underfloor."

Thanks EdSnow & Udash for reply!
