Andy, do you know if your gaskets on the ceramic part of the burner are damaged? I managed to service mine and dismantle the burner all fine without doing any damage to the gaskets at all. Good job as they're aren't available - although I suspect I would have resorted to making my own somehow if that had of been the case.

Hi Andy, I tried in vain to find the ceramic part and gaskets - failed.
They (LR and Webasto) annoyingly just dont break the burner down further in terms of parts. It's even hard to find the glow plug ass'y.
Shame really, as there's a growing community of people (not only LR) that are actively breaking down and servicing their burners.
Tried to hunt down via some Eastern European suppliers but that turned up blank too.
I resorted to finding used burners on ebay to 'up-cycle' parts that weren't available new.
Seem to remember Harold (Motolab) - on this thread - set out a list of new spares available?
Good luck!

Thanks Arb my FBH wont fire up. I've run the diagnostics on it and it all seems ok so I have a nasty feeling the cup may be damaged in the burner.

I haven't plucked up the courage to take it out yet So not sure if they will be ok. Watch this space.....

Thanks mate I did find the whole burner, not sure whether to buy a complete second hand FBH off ebay. It's a gamble.
I'm going to take mine out first and see if it's as simple as giving the unit a damn good clean

To be honest you'll only be taking it apart again with second hand bits. If you know the glow plug is goosed or the burner is damaged just bite the bullet.
You'll be glad you did If you don't already have it the Webasto diagnostics are available free to download. The interface and cables are available from Martin at the site shop!yµ (idµ - eAµ) ψ=mψ

Got the interface and cables that was the first job.
Yeah you have a point it may well be a new burner so maybe worth just doing it. That seems to be the problem no ignition..............

Another tip!
Buy a new burner, glow plug is included... and save money on NOT buying old and pre used ditched FBH’s and also diagnostics....and needed adapters... you do not need it normally.... cleaning, new burner, take the power off (but you did allready when you dismounted it for the dismantlement)
Priming etc. Is is ONLY needed when you fit a complete new fuel line and/or pump and your fuel line is emptied..... so... not when changing a burner or cleaning a burner...
And if needed you can always buy it later...
Another thing..
People spent easy a big amount of money on oilchange and filter each 6K but the FBH who only needs service after more than 100k or more km, has to run on freebees....
Just MHOBest regards

FBH fault code B1D23-13
Hi can anyone point me in the right direction, the FBH has been working up till a couple cold snaps a few months back, I’ve got the fault code B1D23-13 (overheat sensor circuit)would removal and cleaning help clear this fault code. Or would a new unit be the best bet?

Cleaning won't change the fact that one of the temp sensors has gone kaput, but it may be useful whilst replacing the sensor which is the only way to rectify a duff one.yµ (idµ - eAµ) ψ=mψ

Do you know if you can buy the sensor separately, or is the sensor built into the FBH ?

Genuine sensors are available but you need to do a bit of homework as there are a few pretenders out there too!
Another option might be to buy a used unit from a breakers and use that if it works, or scavenge it for the bits you need. yµ (idµ - eAµ) ψ=mψ

my advice, buy new sensors.. OEM indeed...
used ones, are 99% of the time damaged...when removed... removing them undamged looks easy job, isn't though...
so, OR a (used) heat-exchanger with a working set and DON'T remove them, just replace the whole heat-exhanger, OR buy new webasto sensors..Best regards

FBH Occasionally working
Hi,
I have set my fbh to work with third button however it seems to not want to work sometimes. It does run and operate when the ignition is on and engine running. I have also had it work a few times using the 3rd button. Only issue is it doesn't always work and when the 3rd button is pressed all that can be heard is a high pitched whining noise. I have reset by removing the fuse for a few minutes.
I'm puzzled as to what it could be as I know it works, so the fuel pump must be working and it must be getting signal asit has worked.
Any help is greatly appreciated.
Thanks in advance.
Connor

Presumably a rather low battery….
Second it is not uncommon if the glowplug is at a certain age that it needs a second start attempt sometimes…Best regards
