    Hello, just got a 2004 Freelander TD4 HSE Auto with an FBH. Is there a way of turning it off. I thought it only worked when the temperature is less than 5 degrees? But it is warmer than that today and it comes on. It is noisy and smelly and presumably uses diesel. Is that correct?
    Thanks for your help.

    Yes it burns diesel think you can disable it by removal of a fuse

    Anyone know which fuse it is and where. I'd like to disable mine to prevent it from coming on.

    Hi

    It's fuse 5 in the engine bay but I think other stuff may also run through that fuse.

    Yes. Pull fuse 5 in the engine bay fuse box. This is the fuse that feeds the FBH, even though the fuse box kit says F5 is the ECU.
    It's supposed to work, only when the air temperature is below 5°C, and the engine temperature is under 75°C.

    It most likely that the environment sensor (a 5°C thermostat) is fault.
    It will use approximately 1/2 a litre of diesel per hour. But will stop using fuel, when the engine temperature exceeds 75°C. The FBH internal fan will continue to run however.

    Which part are you referring to as being correct?

    In what respect is it smelly? Exhaust fumes?

    If the FBH hasn't been serviced (cleaned of soot), then it can smell pretty unpleasant. If it's been cleaned regularly, then it's flue (It's a tiny oil boiler), smells just like a diesel exhaust.

    Thanks to everyone for your help. When I said is that correct I meant are my assumptions correct, and when I said "smelly" I mean't it smells of diesel when it's running. Can I confirm that I can remove fuse 5 under the bonnet and it won't affect anything else. The handbook says Fuse 5 runs "Engine management, transmission cooling fan and Fuel burning heater.
    If It can be removed can it put back again in the Autumn almost like a switch?
    Thanks.

    You can remove fuse 5 without affecting anything else. ;)

    Why not just replace the environment sensor? It's located at the front of the car, RHS of the lower radiator grill.

    Does the environment sensor have another name, I can't find one.

    The part number for the LR version is JWL000020.

    Or JWL100030A for the older Rover 75 version. Apparently the LR version is more accurate, but I've not tested it to find out if that's correct.
    Hope that helps.

    Found one thank you. You sound like you know what you're talking about. Can I ask another question. I had a look at the fuses under the bonnet to check where fuse 5 is. Whilst I was there I noticed that fuse 3 is missing. Is that a problem and should I replace it?
    Thanks.

    There's no reason to assume that every fuse position has to be filled on every model of the FL1. My own TD4 auto is missing 1 fuse (I can't remember which one), but I've used the output from the missing fuse, to feed my FBH remote controller.

    I`ve been scanning through these replies, so thanks Nodge68 seems some of my questions have been answered.. A recent purchase is my 54 plate TD4 auto HSE and I`m slowly going through things on it.. The FBH works very well, but seems to be on for far too long, although, I do have the R5 thermostat trick kit to fit to ensure the engine temp does rise to its correct 88 degrees c soon.. If that does not fully cure the FBH burn time I just may wire In a switch, but, hope it dont get that far.
    As a once landyzone contributer I owned an early 3 door Disco for 10 years but due to disabilities she had to go, so now gone the smaller hippo route.. Loving my hippo now, but will love it more after various things I want to "Improve" through wear & tear over the years..
    Am "not so well" but been round vehicles since I was 17, but have only reached just 71 years now = so my mechanic speeds are somewhat slower now.... LOL.... thanks...Ian.

    Hi again, As I always do, I poured a whole bottle of REDEX diesel system cleaner on half tank of diesel and ran the hippo for a few days on short runs, but topped up with more fresh diesel.. It seems to run better after, but left me wondering if it cleaned out the burning chamber of the FBH.... thanks, Ian

    Well, for reasons unknown as yet my FBH has stopped working, and yes did fit my aftermarket 88 degree thermostat which holds the engine temp in the centre of the temperature range on the gauge nicely now.
    I`m now noticing why they fitted the FBH to aid engine warning up as I do lots of local short runs.
    I suppose I should look at fuse 5 before I look at anything else first, but from there if OK will be a general look and see I suppose...... Maybe try and check the air temperature sensor behind the grill also...
    We will see.
    wrong time if year for my old bones really..lol
    happy new year all very soon.

    The ambient temp sensor will not be the problem, it will be your FBH. With luck, it will be a PCB fault, this can be done with the FBH in situ, everything else, the FBH will have to come off.

    They do fail sometimes. However the FBH will only run if the air temperature is below about 5°C anyway, so unless it's below that temperature, it's difficult to tell what's up, unless the FBH is being triggered by the auxiliary input.

    on my old car I got fed up with the FBH so I went under the front bumper and just pulled the plug as F5 did not seem to do anything when I pulled it

    I want a FBH for my hippo, but never seem to see any coming up at reasonable money :-(
