Flack,
Im impressed job well done though i think you have just voided any waranty it may of had
Now what connections are required for the led from the fbh? Oh and if you get time which wires have you run to the aux batt just for future reference?

Yes it seems that some FBH will only run to a set 30 mins, and Daniel from Danhag has also mentioned this on the board.
There was some software knocking about that let you get in to the FBH, I think wiggs has a copy of it, might be worth trying to get hold of this bit of software and see if you can change any of the settings.
Webasto seem to have some diagnostic sofware. Indeed this was discussed in another thread.
I found a link to this manual. Interestingly this manual mentions the burning time. But as I read it, you need some additional hardware to change the settings. So I think I have to find a webasto specialist owning this piece of hardware to change the burning time setting.
This manual can be found here: http://www.techwebasto.com/heater_main/the..._V2.11.pdf
The software itself can also be downloaded from webasto
the thread about the diagnostics software here: http://www.disco3.co.uk/forum/topic43944-135.html
Concerning the vents. It seems that no vent valves are operated by the danhag system. With a running engine, I set the vents on the windscreen. Then turned off the engine. Then I turned the fbh on. Now all air did come from the windscreen vents.
Apparently the fbh starts with the vent valves in the exact position where the hvac left them. It does not move them
Flack, do you recognize this behavior or does the danhag system operate the valves in your car? If so where is it blowing from?
Do you remember which of the wires was responsible for the cold air?

I think the unit does move some valves or flaps when it operates the FBH, I think thats the reason the car does a system reset when you start your car after the GSM has run the FBH. You can check out the HVAC with the self test by holding both the vent and econ button in while turning your ignition on, this will tell you if you have any errors, as posted by Wiggs a few pages back.
Yes it was the black wire to the green & white wire, this wire closes the car vent so it stops the fans drawing in cold air, if you sit in your car and have your ignition on and touch the black wire to the green & white wire you can just here a thump as the motors shut the vent to outside.
this is what caused me to have cold air coming in as this wire was a bad connection ( scotch-locks)

With our experience of there posting methods I don't hold out to much hope of warranty lol... beside all I have done is open the GSM which you have to do to insert the sim card and extend the LED, not touched anything else.
To find the best wires to use on the FBh look at this post as this was the original fit of the operation by phone method. it shows and tells of the connections to use. I think in my earlier post I mentioned the fuel pump when it should have been water pump that you can use for the LED.
GREEN arrowed plug contains the FBH coolant pump wires. RED arrowed plug contains the W_Bus, CAN bus and aux diesel pump wires . It unplugs by releasing the plastic lock arms either side. BLUE arrowed plug contains the 12vfeed and GND to the FBH. This unplugs by releasing the plastic lock arm on the right side. The Disco3 is a perfect fit!

Flack,
I don't think there is a problem with my hvac as when the engine is running all works fine. when i press the proper buttons the wind direction changes accordingly.
It is just that the danhag system doesn't seem to move the valves.
Where does the wind come from in your car?
Last time I got warm air again but I will check the black on green/white wire soon to see if it might be troublesome.
Could it be that this wire also should control other valves?

Now all working fine and I am very pleased with it so far. I have positioned the GSM unit on the transmission tunnel by the drivers seat, held in place with velcro, which means I can see the LED and reception is good.
If you want to stop the unit early do you just phone it?
Do you also phone the unit to reset a red fault LED or do you have to unplug it?

glad you got it sorted bud.. yes to stop it you just phone it again. As for a red LED reset I have had to do both but more often than not its best to pull the fuse and reset it.
I have found if you ring ti while sat in the car it will fail and popup a red LED.
I have just wired the green wire on the GSM to a switch so can now fire it up anytime and it works just the same as though you have called the GSM.

the aircon red/yellow wire controls the air flaps. at first i wasnt getting any air flow to the screen or at the front but after redoing the yellow wire and green wire connections to the cut red/yellow, everything was fine. scotch locks not good for these thin wires unless you bare the wire and fold back on itself and ensure contact with metal clip.
I have no harness and also use the wbus converter that i've had for a year rather than the pro version of the gsm unit. the converter uses ttv standheizung mode.
i used a 60 min. burn to completely remove all frost and snow (5cm) from all windows front, back and side a couple of days ago (-5C). car starts so easily when warm, really warm inside
well pleased There's one wheel on my wagon, but i'm still rollin' along, it's the cherokee, they're after me, but I'm singing a happy song

Nice 1 arhrrs and dickdastardly welcome to the defrosted warm bum section hehe.
I've found that the red led seems to either reset or if you phone it or ask for info? The switch that ive installed like flack does work well without phoning but i have found both phoning and the switch tempremental if you try and use them on a second run to soon after the fbh has just been running. It seems like some cooling down or resetting is required before switching it again?
Flack - which wires have you taken to the aux batt from the danhag system? Did you take it straight to the batt terminal?
Mine seemed to run much warmer the other day when i altered the fans to start 15mins after the fbh had been running so trial and error is definately recommended.

I agree it was late but not as late as the post says? It was 1 hour earlier as i was off to bed. Think it might be when you reply to a post from a country on a diff timeline? Anyway i can lay in on a sun morn hehe.

I have a wire running from my aux battery to the back of the car, I just cut in to this and used a double mount fuse box, used one fuse to the GSM and the other for my things I need to plug in at the rear of the car.
The wire is the red wire that connects to the green & purple wire on the small plug on the HVAC panel.

I wish we could get a 60 mins burn since the max we can achieve is 30 mins... need to look at this and see if we can alter the time.

Checked the wires, that are supposed to move the flaps. All seem to have a solid connection.
Still the danhag controller does not move any flaps or valves to direct airflow to the windscreen.
But also still don't know if the danhag is supposed to direct airflow to the windscreen or any other vent for that matter.
Send an email to Danhag about it. Hope they answer this time.
Also I assume that, if the cut red/yellow wire would not have a solid connection on it's ends, there would also be a problem with normal hvac operation and I am not experiencing any problems with that.
Nevertheless I hooked up the Faultmate to the car to see if there are any error messages.
Strangly the HVAC ecu showed 4 error messages about Exhaust Gas recirculation things. It made no sense unless I would replace the words "exhaust gas recirculation" with "air recirculation". Then they could be messages that are caused by the Danhag intervening in the HVAC to try and move some flap. Not sure whether they could be expected as the danhag is intervening in the car's systems or to be worried by these messages.

Is this not pointing to the EGR valves, did you reset all fault codes and then run the FBH, I had quite a few errors on my car when I first checked it, but when I cleared all the faults run the FBH and then did another read in of fault codes I had none, I even did the self test on the HVAC and all was ok.
All as I know is that if the red yellow wire is not connected I get cold air all the time, connect the red yellow wire and it works great.

Flack,
Wouldn't it be strange for the HVAC to report these errors about the exhaust gas recirculation. I would expect them in engine management ECU?
I had cleared all the errors then switched off and on the ignition key without even starting the engine and then these errors returned. I don't quite remember if the fbh had run somewhere in between but that could be. I'll retest that.
One error is about some valve motor position. I remember reading somewhere that when the danhag operates the air recirculation valve, it thus leaves it in a different position than where the car expects it.
