My FBH doesn't work, fault code says the water pump of the fuel burning heater is defect. I see some offered on eBay for something like 150quid. If I buy one of those used units, do they include that pump, or is that a separate item? Does anyone have experience in having had this issue?

4.4 TDV8 2011 2011 L322 Vogue SE 4.4 TDV8

Separate item I believe, have a look on lr cat in wiki section.

I also have a similar code on my 4.4.
B12A6-15 (2f)
Aux heater water pump- general electrical; failure - circuit short to battery or open.

My FBH sounds like it starts and can run several times over but never gets warm.

You can hear the pump running but I've not checked if it is pumping.
You can buy new pumps fairly cheap.

JNC - did a new pump solve your FBH issue? Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Yes it did.
I got a slightly different pump. Needed to swap the inlet/outlet part and the plug. (Not sure if i was sent wrong pump or ordered wrong but i just made it work)
But once fitted, fixed the issue.

Edit -
I originally thought it was the pump in the engine bay (you could hear this running) as i wasn’t aware fbh had its own.
But it was the pump attached to the FBH itself.

Is that the part I assume? Did you fit that to fix the same fault code?

No, I had another problem (combustion chamber death). I replace Webasto compleatly, install brand new. This pump is from old original factory Webasto.

JNC - can you clarify this as I’m now confused. Did you change the little pump bolted to the exterior of the FBH to cure your issue? Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Mine was the pump attached to the FBH.
