Had a word with another breaker, apparently they are a common fault, and he reckons I only need it of it goes below -20 c, so I’m off to do a bita disconnecting!!

The FBH only works at 5 degrees or colder and when the engine is running. It's a very useful addition to the diesel 75/ZT. With a couple of mods you can add a timer or remote to warm the car up before you get in....

OK,

But the engine doesn't need to run

Yes to the first part and no to the second...

I guess you want to know if the beast works !

Try this:

-Engine cold and stopped

-At first, unplug then replug the power connector (or fuse F8) in order to reset the system.
-Connect permanently Pin 3 to earth. (To + batt in case of older model)
Simultaneously start a TIMER and listen when the fan stops

IF stop after 3 sec, restart 4 seconds later and finally stop at 2 minutes 7 sec;
The error generated may be caused by:

-Battery voltage lower than 10 volts
-Glow plug open or short circuit
-Circulation pump open or short circuit
-Fuel pomp open
-PCB defective

IF stop after more than 2 minutes 10 sec, then
PCB and all devices are good (except doubtful glow plug)

IF stop at 4 minutes 5 sec , Glow plug resistor too high (0,6 ohms for instance),

IF stop at 4 minutes 40 sec it is a ignition fault, (fuel pump priming fault)

OK,greeners

We don't speak about the same thing.
I mean one can always run it by applying the good voltage to the good pin.
whatever the engine be running or not.

I know you probably know what it is by all the replies you have had, my querie is how did you know you were having trouble with it if you did not know what it was or did, unless it was leaking

[FrenchMike]

Mystery !

I a afraid,
Lot of newbies don't know what is a FBH Webasto !

yes it was leaking, pool of diesel under the tank, had originally thought it was the tank leaking but after a bit of investigation i discovered it was this pump for the FBH
