Chaps

Just by way of an update - the replacement pump I ordered arrived from Germany over the weekend while I was away. Just opened it and it has no wiring loom attached, merely a multiplug connection point

I am currently trying to source a loom for it or failing that a multiplug. I can of course cut the loom off my old pump (they're internally jointed ont he earlier pump) but that doesn't solve the plug connection.

Watch this space.

Apologies for the slow update. Dropped phone incident kinda messed up the pictorials so apologies at the quality of what follows!

So I had to do a fair degree of digging to find what was the correct loom to fit the circulation pump. There are a few variants. The problem is that webasto seem to use both an item number and a part number......
Anyway, the one I used was 1320273a or 9017684c. Paid about a tenner plus p and p from PB autoelectrics on ebay, I got a gasket set from them too. Put FBH back together with new gaskets, including a new fuel piper ubber bung - a touch of vaseline helps. Careful as that fuel pipe is fragile. Note the loom positions:-

Well done. Nice write up. All finished just in time for the Spring.  John

Good work and good write up JB

Any chance you could link to suppliers for the various parts you needed, and FBH disassembly images?

@ stan

Is this on the wiki yet ? .

Hi Joe

Sadly the disassembly/reassembly pics are lost in the phone drop incident.
Pump was ebay - this is the current link:-

Loom was ebay - current link:-

Gasket kit from same supplier as loom (PB Autoelectrical), again ebay:-

Theres a vid here that pictorially you can see how to dismantle the unit (far easier to take the pump off mind you):-

Well done JB, and thanks for taking the time to do a write up.
Great forum, great people.

Well done John - succes at last! I am surmising then, that the pump being u/s was stopping the FBH from doing anything else? Can you recall if you could hear your fuel pump running when it wasn't working?

Too damm cold to crawl under mine at the moment but should really gather up motivation!!
Cheers,

The circulation pump not working would i believe prevent the fbh from firing (imagine it would proper boil the static water!).
No fuel pump click when it wasn't working although on the odd occasion the WTT software connected, I could self test the fuel pump so knew how it sounded.
First attempt at firing it up post-repair I could hear click click getting faster and thought waahey! 2007 Vogue TDV8 with 255/55/20's fitted

The water pump on my FBH has made a droning noise for nearly 2 years now. Is this a sign of impending failure or should I not worry? Taking a rest from Land Rovers for a bit.......

Really helpful info JB, thanks so much for taking the time to write this post. My 2007 VSE TDV8 FBH always worked on warmup mode with the engine running in the cold but never ever worked in my 3+ years of ownership for more than a minute when triggered with the remote.

However, I usually now keep fuse 59 removed at all times in any event (since last winter) as a massive current draw will completely deaden the battery within less than 2 hours (including the alarm and central locking). It clearly has something to do with the FBH but I have no real idea what... Perhaps a big chunk of carbon shorting the glow plug?

As an August project I have managed to get the Webasto Thermo Test software connected using a VAG OBD dongle (c.£3 off eb) and a set of short croc clip test leads (c.£2 off eb). I clipped pin 4 of the OBD dongle to the side of the lighter socket, pin 16 to the power feed of the passenger footwell light (seemed easy to access by poking a pin into it and works it with the door open) and pin 7 to the white with red wire going into the rain sensor (the plastic behind the mirror simply unclips). This gives access to the k-line (a vestigial BMW data bus). Selected Thermo top C/Z BMW version and it worked to give error messages and to test components. The ability to actually start the heater was however greyed out, pehaps because it was getting confusing messages on the bus from other no-longer BMW things.

I was able to run the fuel pump, then the glow plug followed by the fan. Bangs like a bird scarer (with a big puff of smoke!) so they all work! I guess once or twice (but no more) won’t do any harm - the FBH as a whole seems to be kaput anyway! The water pump seems to have had it, no matter how many times I tried. The Thermo Test error message is “circulating pump interruption”. I do remember the water used to gurgle a bit in the expansion tank when started, but even that seems to have stopped when I dare to try inserting fuse 59 (with a spare battery to hand).

Maybe this will give soemone, somewhere some clues?

Thanks for taking the time to write this up, I know nothing about modern vehicles and this article is beyond me but maybe one day.
I know it’s a pump, as you have said so, but what is its purpose
Dose it pump fuel or coolant
I know it burns fuel, I know it has coolant
What is FBH
CCF
WTT
thanks

EU29 - it won't ever run (other than the quick tests you did) if the circulating pump is u/s.
Whack a pump on it? 2007 Vogue TDV8 with 255/55/20's fitted

Thanks JB - I will keep a look out for one.

Knares - the circulation pump I am referring to is in respect of coolant. The FBH is the fuel burning heater, the CCF is the car configuration file (not applicable to my post). WTT is either the Webasto Thermo Top (a model of fuel buring heater used by various car manufacturers) or the Webasto Thermo Test software that connects to it from a PC.

Hope that helps!
