Checked every possible bit of carpet for 'damp/wet' - nothing apparent as yet, seems to be dripping out from underneath. Honestly I havent had a 'proper look yet re the coolant leak as yet, will get on to it asap tho.The diesel engines are more forgiving of coolant leaks than the petrols so hopefully it hasn't been overheated. If its a hose that's leaking its no trouble, just replace it. If the coolant is spilling into the passenger footwell, it'll be the heater matrix which is a dash our PITA job to swap, if you have no evidence of where the coolant is going, cross your fingers its not the head gasket or something serious (which thankfully isn't common on the TD4).
Might just get it down to the local landrover garage 'Gratech' next weekend and get them to give it a really anal look over and decide from there the best course of action, clearly I dont wanna spend thousands on it but happy to spend a few quid on it.
