I am fairly sure it is but when i found the engine number it started with 111 not 11L and no it is not my inability to tell an L from a 1.
I have posted some photos of the engine no location and the engine generally for your verdict.
This photo taken from standing in front of my radiator grill, i manufactured the battery tray on the left as this will eventually be the location for the engine battery and the battery under the seat will become a leisure battery.
Engine no location middle right of above photo on horizontal lip behind the timing chain case above the fuel govenor and bolted black blanking plate (sorry i don't know the names for these things)

Picture of offside of engine under my personally made battery tray showing the fuel governor and throttle linkage

High mounted turbo and exhaust manifold, notice how little space there is on this near side of the series engine bay.

It's a defender 200tdi

Thought so, from the location of everything, it was just the engine number that confused me

Turbo and manifolds are worth more than a complete disco motor!
Transforms the series.
Battery under passenger seat makes engine access much easier.
