After years of service - with remote control and blowers working - my FBH started to lock-out. Fllowing errors keeps reappearing and after cca 1-2 days it locks and I need to reset with Faultmate.
NO START- EVEN AFTER RESTART ATTEMPT -:B1D29
COMPONENT FAILURE - NO OPERATION. (INTERMITTENT)
FLAME DETECTED PRIOR TO NORMAL OPERATION -:B1D31
COMPONENT FAILURE - UNEXPECTED OPERATION. (INTERMITTENT)
I tried the FBH test routine (faultmate) - no faults have appeared.
Over this 1-2 days - car is used normally - so during these 1-2 days the FBH starts approximatelly 10-15 times. Then it locks-out.
My next step is to try the webasto diag soft + the K-line kable - however I am not sure if it will bring more light into the problem. Anyone had similar issue? How can a flame be detected prior to normal operation?
Any hints/tips? Thanks2013 D4 TDV6 S; Baltic Blue; IID Tool BT

Mine has eventually started working after a year after a software update the other day yippee
You might want to invest in a diagnostic loom and K-line adapter to use the Webasto diagnostic software
You can run the FBH manually using the diagnostic program.06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

It must be the FBH time of year - my inbox is busy again!
To 'do away' with a few uncertaties:
FBH works with any of the doors open.
FBH works with the bonnet open.
FBH works with the airbag light on.
FBH will not run if the low fuel light is on.
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 when the EXTERNAL TEMP is 5.5deg or below (5deg on the inst diplay)
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.
FBH shuts down when the EXTERNAL TEMP is 6deg or above.
The temp are those show in the Webasto Prog and vary from those show in the Land Rover Manual!
If your FBH is not working, on a day where the external temp is 4degs or lower, the engine won't be able to maintain 'normal' coolant temp at tickover. So when you are sat in a layby eating your egg and bacon butty there will be no heat from the heater!
The FBH errors are held in NonVolatile Memory. So even when the power/fuse is removed the errors are not errased.
If the Webasto oval control is fitted, all errors (including 'lock-out') are erased when it starts the FBH.
Just one thing tho - since having mine activated last month - my Mrs uses it non stop - literally two or three times a day!!! Thinking about the batteries as she only drives the kids 2 miles to school...
Are there any long term consequences if used on such a regular basis?
Unfortunately we don't have Redex here in Norway....
Anyway I made a new breakthough today based on the ansver from 4b4.
After sucessive trials with clearing out faultcode B1D29 and attempting to run the FBH, it shut down after a couple of minutes every time.
Then i used an air compressor with a blower gun into the FBH air intake, and kept blowing after the FBH started...
Appearently with the airgun blowing, the FBH kept running and fault code B1D29 never apeared. I managed to give it at 20 min run until the engine was warm without any new fault codes.
Hopefully this has "de-glazed and cleaned out the residue" inside as proposed by 4b4. I am looking forward to tomorrow morning, it is prognosed -18 degrees...... , so guess I will get the final verdict of the FBH.
Has anyone tried using EGR cleaner to shift the carbon deposits ??

Yes Gary you could crawl underneath and remove the feed pipe to the FBH fuel dosing pump. Fit a new pipe to a bottle of the treatment of your choice and this will be fed to the FBH.
I would perhaps go with one of the non mechanical (i.e. Chemical spray / extra air) methods unless you are determined that Redex is the only way.06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti
