Did they then check the coolant temp to see if it was the FBH or the changeover valve at fault?

I don't know to be honest. I will ask. They should know as a Land Rover dealer I should think.

In my own personal experience I wouldn't take anything for granted.

Just called the dealer who are now saying it works. The pump needed to be reset.
They've tested the FBH several times and it worked each time.
Hopefully it will still work when I operate it!

Well it's all back together and working as it should.

French Mike deserves a medal!

Yep what a ledge
Decent bit of kit when it's working. Well worth the effort

Interesting - if it's that easy to remove, it must be that easy to retrofit (plus different valve block)

Couple it with the SMS box = win

Before you stripped and sent it off, did you hook it up to the webasto diagnostics SW? 

No Dan, 99% of a FBH failure is down to the same couple of resistors failing in the pcb.

Mike has built a test rig that checks all the functions.

Can you imagine how many FBH units have been scrapped and could have been fixed!

How long did it take form posting it to receiving it back?

I have the same problem where I can hear it start to run but no heat comes out and stops after a minute. 2009 TDV8 Vogue SE - Bonatti Grey

Sounds like the same problem I had. Sent mine ti French Mike, took about 7-8 days but was over the Xmas period. I think he says around 4-5 days turnaround. You can still use the Range. You have to connect the water pipes together with a bit of 3/4 copper pipe. I plugged the fuel line just in case, but I think because the FBH is out it doesn't demand the fuel.

Yep as Steve said.

What I will say is don't use poxy Royal Mail Airsure, supposedly 2 day express, my arse.

Cost £10.20 and took 6 days! They don't guarantee the time, just do there best!

Mike returned it cost him 1.85 euro and took 2 days!

Ok great thanks. Looks like I've just added another job for the weekend.

Could you PM me his contact details? Thanks. 2009 TDV8 Vogue SE - Bonatti Grey

So I have just had FBH replaced, new from Land Rover on my 08 TDV8 and the diesel pump, which was suspected at fault first.
The engine coolant is warmed up but no heat in the cabin, fans are not activated to blow the air around either.

First question, Should the remote flash continually for the 30mins cycle to prove the cycle is active.
Mine flashes green when pressed and then nothing although the FBH kicks in.

Second, is there anyway to check this is working correctly without the ambient temp being 7c or less. I am so close to getting this damn thing working, but seem to be held up by warmer weather

Third, is there any way to check the change over valve, where is it located and what is it changing over i.e. coolant flow or electrical.

Many thanks in advance

Same for me, had my FBH replaced by a new one from Land Rover and it still doesn't heat up the cabin (it is only blowing cold air even when cold outside). It should blow hot air when the outside temperature is below 15°C not 7°C.

I believe the activation temp / run times varies depending on MY
