2007 Range Rover Autobiography TDV8 Zambezi Silver

Coolant pumps and Fuel Burning Heater

Need a bit of a steer on the number and location of any coolant/circulation pumps on the TDV8 3.6 2007.

Reason being; I'm getting a "0x0304 Circulation Pump open or short circuit to battery" fault showing up in IID. FBH is running for a bit, no heat, then it turns off.

I'm assuming there are possibly 3 coolant/circulation pumps on this vehicle ?

1. The main water pump - I know where that is !
2. Auxiliary water pump ?? - I don't know where this is or even if it exists !
3. FBH Coolant/Circulation pump - I think this is near the main FBH unit - but I'm not sure if this and the Auxiliary pump are one and the same thing ??

Any explanation gratefully received

Thanks, but already looked in it, it doesn't help much as its ambiguous. Hoping someone might have had hands on with these parts and can clear it up for me.

There is a coolant pump just below the double coolant valves located on the RHS of the engine bay.

Click image to enlarge

It's item 14 on the above picture and is mounted on the same bracket as item 10, but located underneath it.
Is this the one you're looking for?

The first picture is the double coolant valve you'll see first, with two rubber hoses feeding to the heater matrix.

EDIT
Is the engine running with the FBH on, or is it off? If the engine isn't running then the fault may most likely be with this pump, No. 3 on your original post.
