Can somebody help me ? My RR TD6 2003 is not running the FBH when the motor is running.
It works fine with the remote and the screen as long as it is in parking heating function.
When the motor is running I can select the aux heating the led is flashing but the heater is not working.
It is -15 here and I can't get the motor warm. Is there a way to activate it directly? I can activate it to put 12v on pin1 of the 6 pins connecter of the FBH but this only works when the motor is not running ?

Finally sorted it out thanks to webasto software and IID Tool
Was 1 fault in the webasto ecu
Due to the all comms software it changed my settings so aux heating was no longer activated
With the IID Tool it was a peace of cake to reactivate it
Btw the same for the front parking sensors and the remote opening of the doors

Just posting it if anyone is interested could not find it in any other posts

Hi jak,
Glad things worked out

I do have a question, tho: did you make any changes relating to the FBH on AlllComms or how do you know that AllComms is at fault for YOUR aux-heat function not working?

Before I used the all coms the FBH was working normal
The remote opend all the doors at once and the front parking sensors where active

After I connected the all coms and selected the vogue standards these things where altered or not working anymore.
Using the IID Tool you can reconfigure the car as you know.

I think that the all comms uses standard for a petrol not a diesel ( this is only a guess )
