made the 300 mile round trip twice to drop off and collect my range from the guy i brought it from to fix the FBH.

Southampton to bLakedown near Birmingham... dropped her off monday night back up again wednesday night.. promised fbh was fixed

Well it worked yesterday eve, but fired it up before work this morning and it ran for 5 mins and then stopped..

Well it was still running but you could hear that it wasnt burning fuel just blowing one thing i think ive learnt is the difference in sound between when its burning and when its blowing..

Why wont this thing just work?

Do you have to hold the on button for a few seconds or just press it?

It becoming a thorne in my side  Regards

In my 2011 , the FBH is much quieter than my 2007. Is there no heat in the interior ? 2015 4.4 AB
GSXR 1000 K5
R1 1998

When i got in the car it was blowing cold air Dolph.

Can you unlock and get in the car and will the FBH continue to operate? Will it only shut off once engine is started?

Also FBH fob still blinks green once the FBH has shut down?

Why is it so complicated lol Regards

My FBH stays on when you unlock the car and get in. Used it yesterday morning and can distinctly recall feeling the warm air coming out the dash vents when I got in. Think it only goes off when you start the engine

Sounds like yours still isn't right, sorry to say. 09 RR Westminster 3.6TDV8 - Stornoway Grey / Black interior - now gone (sad face)

My thoughts too,

ive never felt any air coming from dash vents either always seems to blow from foot vents? Regards

As Tugger says, if you start the FBH with the remote it will stay on when you enter the car. It also stays on when you start the car until the coolant temperature reaches a pre determined temperature. MJDronfield put up the operatiing parameters in this post

https://www.fullfatrr.com/forum/topic50325...p;start=15

Have another read through and see if you can work out where your unit seems to be failing. Pay attention to the voltage requirements towards the end. If your battery is iffy, then the voltage may fall below the level where the FBH shuts down to still allow you to start the car. Put a voltmeter on the battery when it's running to see what happens to the battery voltage. Don't start the car during this test. You can con the car into thinking the bonnet is closed by placing a weight carefully on the bonnet switch, lock up the car and let it go to sleep and then try your remote. This flashes green for a second or two when initiating the FBH, then blinks slowly whilst the FBH is in operation. The fob blinks red when you shut off the FBH with it, and doesn't continue to flash when the FBH is off.

Also, ISTR that if you haven't enough fuel in the tank it shuts down or doesn't start, but that may be . You can hear the pump for the FBH running (click, click) if you stick your head close to the rear of the car, (not sure which side) or in the load space area.

Make sure the fuses for the various bits of the system haven't blown. There are also things like filters in the pump inlet and an igniter and water pump and fan in the FBH, as well as changeover valves on the rear of the engine bulkhead. You don't want to be investigating those until you have checked all the "easy" stuff first.

Let us know how you go.

Just read your last, vent operation is in the info linked. Cheers

Does the fbh exhaust get hot just from the engine running? Regards

Can't see why, it's not connected as far as I can tell.

Having said that the coolant should circulate through the FBH at all times so you may get some heat conduction, but not, I would expect at the exhaust end and nothing like the temperature I would have expected from an FBH exhaust. Cheers

Any reason having the bonnet open when turning the fbh on would make any difference???

Was testing battery today with my dad when I decided to try and fire the fbh up to show dad what is was / not doing.

When suddenly it WORKED??!!

it turned off after 5 mins or so but the cabin was proper warm. I’m guessing it turned off early because of the ambient temp??

Question is why did it work now and not all week after being fixed?

Did the bonnet being open have any effect!?? Regards

Don't see why the bonnet being open would affect the FBH, but it is a FullFat

As to ambient temperature, Southampton got to perhaps 12-14C today from 1200-1400, but that seems a little way from shut down ambient. Info I have doesn't indicate it shuts down on cabin temperature.

How was the battery voltage before/during/after the FBH shutdown. I think you say you do a mile to work, that's short journeys in the week, have you done a longer one in the last 2 days. Battery charge levels may be a factor. So could things like the state of the ignitor/flame sensor, combustion fan etc.

Perhaps time to have a chat with a local indy about this. It can be difficult to diagnose from a distance, and I'll the first to say that I'm not the best

A final hope, you said you bought the car near Birmingham, was it from a dealer? If so you do have recourse to have them repair it under consumer protection within six months, ISTR. Cheers

Ok interesting discovery tonight today

So the fuel burning heater comes on and works with the engine running. I have read that this is to help the engine warm faster and reduce wear.

I physically felt very warm air coming from it’s exhaust when the engine was running so the fuel burning heater does work and so must the glow plug etc. Otherwise it wouldn’t be able to fire up with a cold engine.

So it stands to reason that either the module or a temp sensor is stopping or someone has suggested to me the webasto water pump could be seized

But something is stopping parked heating working??

Ps. Battery voltage 12.04v engine off. 13. Something running drove to Birmingham and back this week. Apparently they fixed it Regards

Sounds a fair set of deductions.

I would assume if the pump fails the the casing overheats, and most likely the FBH enters lockout. That requires a diagnostic reset, or the power removing for 10seconds+, (battery disconnet or perhaps fuse.) If it's running wiith engine on then it appears that the pump is OK.

It does look like a code reading may be needed. Cheers

With this lockout thing I don’t understand if it is locked out does this in turn mean that it won’t fire up with a cold engine and this help the diesel warm up faster to reduce wear??

Yeah it’s going to have to go back to the garage for sure.

Think I’m right though that the heater itself is working. Regards

If it enters error lockout, it needs the reset before it will run again.

The part of the manual in the post referred to earlier has info right at the end about the error lockout and reset and how the event timer is slightly different, but will result in error lockout if it reaches a count of 3.

Yours runs, so hasn't error locked out and seems to be working.

Good luck with the garage, you may be able to negotiate them allowing a local to you to do the work, but get them to arrange it AND get it in writing before going ahead. You may have to let them have at least one more go, but push for expenses and a courtesy car.

Let us know progress please. Cheers

Just looked agin at your post. You say 13 something on the run to Birmingham. That doesn't sound to good. Mine runs at least 14.5 at tickover once settled in, wiithout moving the car. You need to start looking into battery age, charging circuits and alterantor. charge the battery overnight and try in the morning.

I had problems last year with various things, the alternator voltage being well down at 12.5, so the battery was not charging.

From my post last March after changing the alternator.

Checked the voltages the day after she came home and found it at 14.8 after starting, then dropping to 12.6 as loaded with all the electrical bits, (lights, AC, screens, seats etc.). Revs to 1000 and the voltage recovered up to 14.6 then at 14.6. on tickover. Seemed good

Next day started, after a few moments at 14.8V then down to 12.1 as loaded up, stayed at that until electrical load removed and returned to14.6V. Took a run to warm her up, 14.9 dropping to 14.6 with all the electrical bits on, off and on again. That looks as if the replacement alternator has done the job. I assume the figures after start and while cold reflect some sort of "intelligent" charging.

good luck Cheers
Richard
