Fuel Burning Heater Issues
History:
FBH has worked fine since new but had a few slow starts (relights) at the end of the winter that were cured by Redex. I installed a BAS FBHC in the summer and again it took quite a few goes to get it running after being dormant since the winter, but Redex and persistence paid off. I made it a habit to run in every couple of weeks or so to keep it clear and all was well, lighting on first attempt.
Now:
I tried to get it running a couple of weeks ago but it must have taken 10 attempts (30 relights) over a few days before I got it going. After the first good burn yesterday it started and ran again first time but since then it has failed to light.
Voltage is good, fuel level is good, fuel has Redex in it and the sequence seems fine. It runs until it gets to the 'almost stable' stage and then snuffs out and goes through the shut-down cycle. With the FBHC it attempts a further 2 relights with the same results before finally shutting down. I am so glad the FBHC clears the lock-outs as it goes otherwise I would have never got this far.
Everything else looks and sounds ok. The start-up sequence seems fine; aux fuel pump, fan, ignition stage, intake whoop-whoop noise but she is rather reluctant to keep going.
Any suggestions from the FBH massive?Land Rover - Turning Drivers into Mechanics Since 1948
Can you get someone near you who has a FM and run through the test routines to see if that brings up any faults, or if you have some either spray try spraying around the intake when its nearly up to speed and see if this helps it to run any longer, if it does then it could be fuel related.

Not sure anyone near me has an FM but I hadn't thought of using ether down the intake. I'll get a tin of easy start tomorrow but is there any chance of damage using it on such a small device?Land Rover - Turning Drivers into Mechanics Since 1948
No bud just don't over do it don't spray directly up the intake just hold it close so it can be sucked in..

Sound like the heat sensor isnt working, The glow plug stays warm for the first part of the prosess untill running then it acts as a flame out sensor so if it is not sensing the correct temp it will shut the FBH down as it thinks its not burning.
this could be down to it been covered in crud or that its overheated using redex ( redex burns at a higher temp to burn excess crud from the engine)
You can strip down and clean but its a time consuming job.

I've had mine started a couple of times with the faultmate - once in the Pyrenees when it then proceeded to work correctly all on it's own once - then not again.
Had it purged again the other week when it ran and smoked the carpark out - but on a subsequent run it barely ran, though no faults were reported on the FM.
Thinking of A) getting Pete's remote FBHC and B) putting some redex in the tank.
I am putting off A) because I don't want to find that the FBH is f d anyway.
But testing it is difficult without it Mark.

Mine isn't firing either, it does nada, I'm not sure if I'm meant to hear anything when it tries to start up but on having the bonnet open after starting the engine there is not a peep I made sure there was more than a quarter tank in it and it was 3 degrees outside but nope nothing at all.
I'll have to pop it into the garage sometime soon and get it peeked at to see what the issue is.

Hi sopjas, the symptoms are as you describe so I hope its just crud. Managed to get it to run twice today, but this was after many start attempts. Oh and I now reside in Gainsborough having moved from darkest Wiltshire.
Not sure what I would have to strip down to clean it all out. Presumably I would have to drain or part drain the coolant to strip the FBH down. I need to find some technical documents before I resort to open-heart FHB surgery. Anyone done this before?Land Rover - Turning Drivers into Mechanics Since 1948

Try priming the fuel pump on the FBH, then restart it. It made a big differance with mine as I always used to get failed starts, then I got the BAS kit and it has been ok after I did a prime and a couple of full 30 min burns. Regards Jonathan

Hi Flack,
I've got the same documents but nothing that shows the internals or serviceable parts of the FBH itself. I'll google around some more for Webasto documents and post-up anything of relevance. There has to a guide somewhere!

I removed mine, Jusy get hold of a little bit of pipe arond 2-3 inch long and join the coolant pipe together, this way the car can be used without theFBH fitted.
I just stripped down noting very carefully where all the parts where remove, take photos if nessessery.
I have sorted these problems on another FBH by removing the exhaust and the air filter pipe and then blowing compressed air through, (wear goggle as the amount of crap that comes out ) this seems to have sorted his problem.
I will try and find info for you that I used.'Just because you're breathing doesn't mean you're alive'
