I just read an ol dpost from Stu....Pull the fuse out for 10 mins (until the car goes asleep)
Will try that later on today...
I only pulled it for a few seconds.
Pulled the fuse for like 15 mins......put it back....tried it...
no luck.....FBH not kicking in....

Let us know how you get on Matt. Now mine is working for the first time in 12 months, what a difference it makes...

Just got mine back from the dealers and the FBH is now working! The engine now warms up in just 2 to 3 miles unlike the previous 10 miles +
I need to check what they did but it wasn't just a simple reset - i suspect they had to clean it out or replace it. I had various other bits of work done at the same time so forgot to ask...mainly had a mis-fire problem on one cylinder...
Anyway, plumes of smoke from under the bonnet now on a -3℃ morning

I was told last night that the FBH have their own Glow Plug and that this particular one on a FFRR had failed and was being taken out to go to a specialist diesel centre to have a new Glow Plug fitted.
Maybe some of the more techy guys can confirm or deny this, as i had never gave it a second thought as to how the FBH ignited its self.ATB

I am more familiar with the Eberspacher hesters but I think that they are similar to the Webasto used by Land Rover.
The burner consists of a gauze which is initially heated by a glow plug. Then the fuel is fed onto the gauze and should ignite. Once it is alight the glow plug is switched off. When the unit is shut down again, the fuel supply is stopped and the glow plug comes on again to ensure that any remaining fuel is burned off, leaving the gauze clean. There is also a fan that passes air through the burner and onto the heat exchanger to heat the water.
There are various sensors to monitor that the heater is working correctly. One detects whether the fuel is ignited and another checks that the system does not overheat. Because the glow plug requires a high current, the battery voltage is also monitored. If the voltage is too low then the heater will not operate to reduce the risk that there is insufficient power for the starter motor and other, more important circuits.

So I spoke too soon, several days of below zero temperatures and it's not working, been through the "reset by pulling the fuse whilst ignition is on" malarky to no joy.
I'm now reading things on the forum about the following being causes of this too:-
1) if parked on a slope
2) if a door is opened prior to ignition of the FBH or during FBH running
3) poor battery condition
Can anyone confirm or deny any of these?
Maybe I should one of the fault code reset things? Would that help?
Cheers

Matt
I can confirm that with mine (which is an earlier model) if the doors are opened at any stage when the FBH is on, or is priming itself to turn on, then it will shut down. I have also discovered that mine will not operate unless the heater is switched on. I cannot comment on the hill parking suggestion. Since I fitted the oval timer I have had no problems at all, even with low fuel cold start ups, it will not come on, but as soon as i refuel it will. My advice is to get a timer, its simple to fit and comes in at under £80.00. As I mentioned previously, I believe they do get gummed up, especially as it is sat idle for a lot of the year. so as soon as I got mine running, adding redex when I refueled on one occasion seems to have cleaned it out. When I have the funds I am going to invest in BBS's Faultmate, Good Luck

Thanks Matty 2332, I shall try it again without opening the doors...hang on, how do go outside to check it's working....
Where does one purchase the timer from?
The faultmate sounds very useful though if anyone has one around the Sheffield area I'd willingly swap a few "folding beer tokens" for a quick go?

I got mine from a chap in Guersey via Fleabay, I think hes one of a very small number of sellers. Good luck !
Mine did work on a slope - doesn't come on at all at the moment.

That useful chap Wiggs has the technical manual for the FBH posted here:-
Gives the exact voltage details (and other details too) that can cause a lockout.
I'm going to get my multimeter out...
I think I also need to read the fault codes...

Had my FBH re-set by dealer a couple of weeks ago.
However reckon it's not been firing over the last few days.
Just been out to check and NO ... the thing aint firing!!
Why is this ..... especially after a re-set ???
just tried the 'fuse out' procedure and no joy I was a normal heterosexual chap, but in these new woke awakenings I now identify as a Wardrobe.

FBH under interigation ....
So my FBH has worked OK until a few weeks ago.
It is one of those things that if you don't have it you don't miss it, but if you have had it you do miss it!
Things arn't as rosty toasty as they should be for some miles.
I may have run the diesel low - like off the guage.
Avoiding the dealers, I met up with Wiggs and his faultmate and the FBH errors and the lockout cleared.
It coughed and spluttered back to life only to fail a wihile later.
Hmmmm.
Couple of emails to a friend of a friend later and I find that the 'W-bus' is based on ODBII 'K' bus. Well it would be the Webasto is German and so is the K bus.
What should drop in my inbox this am but the latest Webasto Thermo Top Test PC prog with W-Bus support .. ask not from where that came.
This morning was spend modifying an ODBII /USB PCB to make it work with the W-Bus.
A short while later and out to the car with my interface and the laptop. Unplug LR loom and plug my loom in.
Will it work? Fingers crossed, run the prog and .......
Yes! Contact.
Three Errors: i, no start (error 02) [5 times]. ii, no start - interlocked (error 07) [1]. iii, Fault 36 [2].
The first two are obvious - it failed to start five times, so then went into lockout.
The third error 36 twice - could be me removing the fuse and disconnecting the FBH heater power plug ?!
It is worth pointing that the FBH errors are logged in Non-Volatile memory withing the FBH, so disconnecting the power for any length of time in any kind of order will only log up more errors and not clear them. Even if it does say in the Land Rover information that it is in Voltalie memory!
Clearing the errors was successful.
The Webasto Prog gives complete control over the FBH along with live diagnostic info of what is happening, so I fired it up.
The surrounding area disappeared as the excess fuel already in the FBH was burnt - but the FBH worked!
It heated through to 80deg at full bore then dropped back to tickover.
Shut everything down, plug the FBH back into the Disco3.
The outside temp at this point was 4deg so the ATCM should run the FBH.
Start the car and wait .....
The FBH fires up, runs .. Yea
Packed everything up, went and got some diesel. On my return there was a lack of FBH.
Plug everything back into the laptop but this time leep the CAN Bus connection to the vehicle. This way I can monitor what the ATCM is telling the FBH to do.
There was one error: 'STFL' which had caused interlock.
Mmmm.
Cleared the fault, started the Disco3 and just monitored the FBH bus.
It gets the command from the ATCM to run, goes through the startup, starts the burn then a few seconds into the burn something happens causing the FBH to shut down and create this 'STFL' error and lockout.
Disconnect the CAN bus, clear the error and run the FBH from the laptop - all OK
Any idears what a STFL error is - possible a bus error?
This is a snap of the Webasto PC Prog showing the STFL Error:
If anyone is interested have more pics of the afternoons events .!
Will see if the FBH runs in the morning ...
