That unit is very similar between D2 and D3 and incorporates the auxiliary water pump, which has a habit of failing and getting very noisy.
On both my D2's I've had to disconnect power to it as the noise got excessive, BUT the heating still works though takes a little longer to warm up in the cabin.

However, the main point of this is that the pump also drives the circuit for the "Rest" heating function, which I have never ever found a use for.

BUT it's worth testing - get the engine warm, turn off ignition and then try the Rest heater. The HVAC should start up; see if it's warm or cold in that scenario.

As noted above, it's a bit of a mission to change the unit (and expensive) so you do need to be sure that's absolutely necessary.

The D3 dosent have a rest function .. but I think maybe turning it on while the ignition is off serves the same purpose ?

No rest function detailed in the handbook and fuses look all good for the HVAC.

Right then, heater control valve ordered and arrived from eBay.

I see the current one in the car by the ECU to the right and back of the engine bay under the windscreen.

Has anyone got a guide or point me towards anything as I would like to avoid any headaches if possible. Also the wires from the ECU foul it, any headaches if these get disconnected during the swap?

Well scrap that idea for the weekend.

Looking at the part that has arrived its been damaged in transit and the main motor/ pump has split and broken off from the rest!

Right then,


Finally got another Water Pump & Valves of ebay as a tested and working unit and spent a couple of hours today swapping it over.

Its a fiddly job and there really is not much room to remove/ put back all the pipes onto it.

Anyway all changed......


..... and it made no difference at all!

Now either both the water pumps and valves I have are faulty or its something else that is causing the problem

Hmmmmmmm have I missed the obvious and not changed the thermostat?

They are next to nothing for the part, much of a headache to change on the v8?
