A revised version of the thermostat is available from Discount MG Rover Spares, runs a bit hotter than standard, https://www.dmgrs.co.uk/collections/thermostats-and-waterpumps/products/r75-mg-zt-freelander-td4-diesel-thermostat-kit-aftermarket-revised-version

This is what the wifes was like, bit of a tide mark so must hold some water. Grommet for the sunroof drain blocked too.

Peel back the wheel arch liners and clean all the mud out, if you haven't already. Potential rust problem for the sillls.

The engine control module also takes into account the battery voltage for if, and how long, pre-heat is used. Turn the heater/fan off before starting on cold mornings as the PTC heater can draw 75 amps during pre-heat.

Latest disc is about 2015 and costs over £30, not worth it as it's way too basic a system. https://www.safenavishop.com/online-shop.php#!/Becker-Navigation-Maps/c/4458468/offset=0&sort=normal

2006MY Td4 and V6 have a higher gross vehicle weight and a higher maximum rear axle weight than previous models though front axle weight remain the same.

2006MY handbook has the same height for Sport and non Sport models, before 2006 different heights are quoted.

If you've just purchaced it, take it back to the seller and get your money back, or get them to pay for the repair. Did it not show up when you took it for a test drive?

It's on a different circuit than the front 15 amp cig lighter. Rated at 20 amp with it's own fuse and relay in the passenger fusebox.

The metal pipe is bolted to the back of the engine, if you can get the bolt near the thermostat out you should be able to do it without removing the thermostat. I find removing the pump/thermostat assembly together easier than just the thermostat. It's not a hard job to do, just takes a bit of...

The bottom of the plastic guard has tabs that fit on the inside and some on the outside to hold it in place. Thinking back, mine only made a noise when the air con was switched on so I thought the compressor had gone, but it was just the plastic shield catching.

Check that the plastic splash guard hasn't been pushed in and is catching on the air con pully, did it on mine.

What temperature is the engine running at, should be about 88°C Or you could get it running hotter with one of these thermostats, https://www.dmgrs.co.uk/collections/thermostats-and-waterpumps/products/r75-mg-zt-freelander-td4-diesel-thermostat-kit-aftermarket-revised-version

The slit in the terminal connector needs making a bit bigger so it clamps tighter. I use a small cutting disc on a Dremel.

It explains it in your drivers handbook.

Thought the glowplug relay was inside the E-box.

There will be another relay on the bulkhead, check that one for damage as well.

You used to be able to get the FBH as a dealer/owner fit accessory kit. http://www.lrseries.com/shop/product/listing/10467/3346/JEC500320-AUXILLARY-ENGINE-CABIN-HEATER-ASSEMBLY.html

The PTC heater fits onto the heater matrix, the FBH fits behind the bumper. Most cars have one or the other, a few have both.

Reg or VIN into Microcat will tell you.
