It's a flattish 24mm hex plug on the back of the t-case about 1/2 way up, left hand side. You fill it up to that level.
That's a good tip oldblue, I'll get some of those next change. The skinny 24mm plugs are bastards of things for rounding off. I ground down an old 24mm socket so it has no lead in chamfer & gets full engagement on the hex.
