Freelander 1 oil leak from TD4 engine

The last few days I have noticed an oil leak from the back of the engine just past the engine cover drivers side on my 2006 td4 .It is not engine oil it is clear and not as thick as engine oil ,the only things I have had changed is the ird and gearbox oils could it be a leaky filler or drain plug ?I have checked the power steering and brake fluid and they are ok any ideas lads ?

Gear oil from the IRD is the likely cause. But you can't beat getting under there with a torch and taking a look.

This is true which is what I will be doing as soon as we get some dry weather, but if that is the case then fingers crossed either the drain or filler plug will just need a nip up and if that's the case it is going back to who did the oil change

Also take the top cover off the engine and just check the top of the engine isn't swimming in diesel

Ok managed to get the engine cover off this morning and after all that I think the leak is antifreeze seeing the puddle on the floor it looked nothing like the pink stuff in the expansion tank .It looks to be weeping from the bottom of the thermostat casing and running down the black pipe , I have checked the plugs on the ird and they are dry . In the second pic you can just make out the weeping / leak at the casing

When my 2005 TD4 Auto's IRD started leaking, it turned out to be an O ring. Just throwing that in. My local Indy LR garage replaced it, so I don't actually know where you'd look to see if that is the culprit. But acording to my guy, it's a common problem.
