All appear similar and I have tried to use the diagnostic software on all 3 of them. The only on that responds is the BMW and I can read the spec and stored fault codes. The other 2 just hang on the "Initialisation" page. I have tried setting the device to W-Bus and also the Rover and Peugeot settings but no luck. The BMW one responds on the W-Bus so I know the software and OBDII are working fine.

The plan is to try and get a least one working and then fit it to the Land Rover.

Any help from somebody who can guide me with the software/diagnosis would be much appreciated.

As much as i know,the two Rover types run without kbus need.

About the others,i think the software are different and dependant on the car.

What bit I have learned, is that the later Rover version has Kbus, but it is only used for diagnostics. There is software in there which could have allowed it to be operated via K-bus, likely from the Hi-Line ICE system, but it was never implemented. On the BMW I understand it was and its ICE system could command the FBH.

T4 can interrogate via the K-bus on the later type for faults and possibly control it too I would expect.

The later (assuming it is the later version) Rover FBH hanging, probably means the PCB is faulty which is quite common. Mike, for a small fee, can repair these PCB's.

I think I am correct in suggesting that the earlier Rover FBH has no k-bus system at all (Mike ?)

There is much more information on the later Rover FBH to be found, if you click on the link in my sig.

Totally agree Harry,

Consequently,the Rover's have a big advantage :they can be used
as stand alone heating system .

As said above,fit the Rover one and forget the software ...
If the PCB is faulty,(see my diagnostics),i can help...

I have read your thread and found it very interesting. I was trying to get the Webasto thermo test software to run on the heaters before I got as far as servicing or installing them to see if any faults had been logged which might imply I am wasting my time with any of the units if they were beyond repair. Thought the software could guide me in the servicing that might be required.
The Peugeot unit is 2006 so I thought this should work on the W-Bus setting of the software the same as the BMW (2005). I thought all models since 2000 are meant to be W-Bus units. The Rover unit is impossible to read the label but the year does start 19.

To make a Rover unit running,you simply have to connect pin 1 to +batt

Nothing too difficult in the servicing, read this...

Harry and Mike

I see I am speaking to you both. I understand it is simple to get the unit running and all I intend to use is a simple on/off switch. The use of the diagnostic software is really more of a curiosity thing having got it to work on the BMW unit and been able to read any logged faults and historic data is quite interesting even if it is not needed to run or service the unit. Now I have played with the software a bit it is frustrating more than anything else that I can not get it to work on the other units.

My FBH hasn't been firing up recently.

I have the older one.

I connected pin 3 to ground, and ran the test - it stopped after 5 minutes and 10 seconds.

It did appear to fire up about half way through (and made quite a lot of white smoke when it did), and the coolant started to warm.

The unit was serviced by me last year.

The temp was about 5° C, and I have a new uprated LR FBH thermostat fitted.

Thoughts on a postcard.

Hi Jack

To me, 5 minutes means PCB out of the picture

White smoke and coolant warm are good signs

Possible flame out

(if you start it by grounding pin3 ,it't the second type (kbus interfaced on pin 2)

Keep the connection ON while all the cycle

a nearly 6 years adventure !!!
