Mine's not playing either, nothing in -8c this morning! Had errors cleared by TFC couple of weeks ago & it fired up fine. Will try resetting. Any consequences in running with fbh not working apart from slow to warm up???

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.
IanNP - this is brilliant, by the end of it I think collectively we'll know more about this damn FBH than Landrover!
I've got about a million questions but first things first - do you have details of the ODBII /USB PCB that you modified - it sounds like a useful bit of kit.
Secondly that software sounds very useful but I presume it's not generally 'available' ?
Thirdly, I too had been thinking only just at the weekend that my next line of investigation is to find out what messages the car is sending to the FBH that might cause it to lock out. Having read the FBH docs that state it will lockout to protect itself from what it perceives as potential serious damage.
Does your new piece of diagnostic software/hardware give more details than the Faultmate FCR?
I'm happy to help run similar tests on mine - I'm a software engineer by trade and refuse to let this thing beat me (or anyone else for that matter) - if I can get similar test kit setup here I'm happy to spend a day trying all the combinations and permutations....

Hi all,
Thermo test program is a freeware and it is available from techwebasto and dongle is available from eBay Germany .
Diagnose pin is pin#2, same pin where you connect timer.

Could someone tell me when the FBH is running by remote timer is this heating up the engine or just the heater matrix, is it better to install a remote engine starter or a FBH remote, and whats the cost of them both.
cheers tony

FBH heats up the coolant in the engine
Remote engine starters are getting a lot harder to fit with all the security , transponders etcG4 Gone ...but not forgotten

Thanks for that wiggs, what cost would that be to self fit a remote FBH.

Oval timer is about £60 ...remote from maplins are about £20 -£25
Couple of bits of wire and a small box to put it all in ...£3 - £4
Great post from Ian, anyone any ideas them what causing all our FBH to shut down ??????

Sounds ok iam ok with a soldering iron is there a wiring diagram thread on the site , and a parts list as i feel like having a go can't be harder than a complicated heating system can it

would it have some thing to do with the fuel, in my game i look after about 50 aga.s which have been failing before there service time , this is due to bad kerosene and lack of sulpha which cokes up the burners

Well this morning was too warm here to try th FBH 7deg!
I had to wait until 3pm before the temp dropped below 5deg!
Jump in the car, sartup the engine and after a few seconds the FBH starts and worked perferctly.
The car was toasty rosty after a mile.
Interesting that the STFL error has not re-occured ... yet
All I have done is leave the vehicle overnight.
I gave it a does of Forte diesel cleaner. I guess what you shold clean it with is yet another topic and as I'm electronics/programming then not one I can comment on!
There seems far less smoke when it starts up though!
Having a play around at tea time I have noted the following:
FBH works with any of the doors open.
FBH works with the bonnet open.
FBH works with the airbag light on (I have a dickie steeringwheel rotary coupler - anyone selling a good one?).
FBH is set not to work with a battery voltage below 10v and above 16v.
There is a 20second delay if the voltage drop below 10v before the FBH will start to shut down.
There is a 6second delay if the voltage rises above 16v before the FBH will start to shut down.
Under control of the ATCM:
FBH starts up in parking heater mode (full burner) until the coolant is 88deg (1/4 to on the temp guage)
Once the coolant is 88deg the FBH drops back to supplemental heating and will cylce between the two modes.
It goes back to parking heater mode (full burner) if the coolant drops below 65deg.
If the coolant remains above 88deg the FBH goes into standby until the coolant drops below 65deg.
The temp are those show in the Webasto Prog and vary from those show in the Land Rover Manual
Yes the Webasto prog is available from Webasto in the link given above and is the same as I was sent.
For those who want a play get version 2.09. This version works with the Thermo Top V fitted to the Discovery3 apparently the earlier versions will report errors on the thermo top V. It has the options of either USB or serial and has the drivers for USB built in.
There is also a PDF set of instructions that are quite detailed.
So once you have the programme you will need an ODBII interface. If your laptop has a serial port then a few transistors and resistors is all you need. Most Laptops these days though have only USB. A usb to ODBII (ODB2) adaptor will cost you around £10 from a well know auction site so it isn't worth making one and theUSB works faster than the serial to the data is updated faster. I have an expensive interface that I use for running and programming radios (£300) on the bench and I have a cheap bright blue interface that I got for programming VAG vehicles. Both work just as good - so go for the cheap one!
I don't think I am allowed to point you to a particular product on the well know auction site so if you can't work it out then PM me.
Once you have the PC prog and the Interface you will need to make up a little loom and off you go.
I will post up some pics of the wiring and results as soon as I get time.

Does anyone know how to use the Disco3 wiki system? If I can get access I'm happy to write up all this valuable info for future generations...
...I'm off to buy myself the USB adapter...
...of course, I'll get the FBH working just in time for spring to arrive and +15℃ temperatures (-1℃ here in Sheffield last night).
Can the Webasto software force a burn cycle without need to wait for next winter?

I guess the delay before shutting down is to prevent the short-term voltage drop caused by cranking a cold engine from causing it lock out?
