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?
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.
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.
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.
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.
