Most likely the rear heater manifold is leaking from a small crack.

When it fails completely, and it will do so under full load, all your coolant will get dumped and your engine will cook.

I would not be driving until I got that fixed, a new engine will cost you $$$!

 

Thanks Naks!
Will look into repair options.

 

Small Update.
Had the heater manifold replaced here in Dubai by my local LR/RR specialist, Euro Experts. They did a great job and the bill was a pleasant surprise at only $300. Was due to the fact that the super charger did not need to be removed as I have a V6..
I have to say that I am pretty disgusted about the manifold quality for it to fail after only 45k km. The bottom and top halves are glued together by the looks of it. The seam parted under the system pressure I assume and started small leak.
attached some pictures

 

Good news. So with the 6 cylinder, the supercharger doesn't need to be removed? Do you know if the Land Rover part has been updated so this doesn't happen again? Is there anything under the supercharger that needs to be replaced? I'm ready to do mine preemptively to avoid failure. Thanks

That's very good to know

 

Indeed no charger removal required for the V6, only for the V8 due to the lack of space.
The most common coolant pipe that fails is the one in front of the engine under the charger, there are aluminum after market upgrades for that one. Mine was the one at the back, i.e heater manifold. This is more rare I understand. No upgraded versions for that one to my knowledge. It was replaced with an original part (looked the same).

 

Thanks for the info. Do you think it would be a good idea to do the front and back preemptively? 2014 60000mi.

 

I definitely think so. Replacing coolant pipes is cheaper than an engine

 

When I had my front coolant pipes done, which were starting to leak, the rear pipe was still in perfect condition.
