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.

Yes its a bit strange, but I have been out playing this morning and have found that if you leave the HVAC on auto and run the GSM you get a hit & miss air circulation.
But if you select the screen vents only on the HVAC panel before you shut down the car and leave it in this position, then run the GSM you get a wonderful air flow to the screen.
So I think its just a lottery where the motors and valves are when you shut down your car totally and let it go to sleep.
It must shut the outside vent flap otherwise we would get cold air, but as for moving other flaps and motors not so sure.
I think if we can remember to select the windscreen only button before shut down when its cold then we will get good airflow to clean the screen. ( If only ) 
I stuck my FM on and checked for error's I had some error's on the HVAc which were related to the stepper motors but once cleared they did not come back after all the tests above. Never seen anything about EGR valves in there though.
I even did the run routine on the FBH and that was fine, just wish we could extend the running time to 40-45 mins though.

Hi Flack
Perhaps “danhag†could advise regarding increasing the run time of the diesel heater, could it be that you only get one opportunity to program the heater? Or can you request the settings from the unit to see if the unit has increased the time?
I take it you didn’t manage to set the unit up via the website??
Very Annoyed I am sorry to hear you are still waiting.

Hi Flack,
I am kind of relieved that your flaps and valve do not operate as well. So either it is a general problem or they were not meant to move at all. I will not be using the Danhag on a daily basis therefor it will be hard to get it in my mindset to press the "air to the window" button every time I leave the car.
Another thing is that, when set to the windscreen, the airflow is much bigger with the same fan speed than when the HVAC was left in auto (somehow it seems to have less resistance), and thus cooling the coolant more, resulting in almost cold air flowing in. I have now reduced the fan speed to get warm air when the vents are set to the wind screen. but this will also have an effect on when I forget to set the vents to the windscreen before turning the engine off.
The fact that my system keeps on generating error messages worries me a little. The more because every time I start the engine, the PROG button is flashing no matter whether the danhag has been used or not.
Funny of you to mention a stepper motor error because that is exactly one of my errors but with the "Exhaust Gas Recirculation" bit in front.
The exact error is: Exhaust Gas Recirculation stepper motor 4 control - circuit low/high.
The other errors that keep on reappearing in the HVAC ecu are:
-Exhaust Gas Recircualation system performance
-Exhaust gas recirculation temperature sensor A - circuit low
-Exhaust gas temperature sensor circuit intermittent - bank 1 - Sensor 2
Considering the running time. On page 33 of this document http://www.techwebasto.com/heater_main/the..._V2.11.pdf something is said about the heating time. It seems to consist of a system level, to be set by a specialized company and a comfort level, to be set by the owner.
I was thinking: If it were possible to alter the comfort level somehow with the oval timer and that this were to be stored in the fbh. And then, when Danhag fires the fbh, this setting is used. As I understand some of you have used the oval timer. Could it be that the folk that have, could have accidentally or on purpose changed the comfort level and so also changed the burning time when using the Danhag system?
This could also be an explanation for the fact that maximum burning times seem to be different for our cars.

I think by the time Very Annoyed gets his Unit climate change will of set in and we will be trying to cool the LR's down instead of heating them up! Lol.
Sorry pal i know its not funny but the german piegons must be on a go slow!

Hi Berndv
I have just looked at the document especially page 33, and I think the telestart is another unit to control the heater, I don’t think its some thing fitted in the heater, but I stand to be corrected if some one knows differently.

Very Annoyed I could hear you celebrating form the other side of the Channel!!!!! (Never mind from the other end of the country)……..
Now just get it fitted and you can break out the champagne!!!!!
Good luck with the fitting let us know how you get on……..

Although I now own a D4 with Timed Climate I've followed this thread with great interest and noted the problems that had occured. Whilst trawling through evilbay I came across this-

If you could pipe this into the coolant system and mount under the glove box area, 12v supply via a relay from your GSM unit you would have a reliable pre heater. Club Exped trailer

Did some further testing on the working of the vents and the occurring of the error messages.
I reinstated the two cut wires in their original factory state. i.e. I put the red/yellow and green/black back together again.
Also I released the black wire from the green/white one.
This stopped my Exhaust Gas Recirculation error messages from reappearing. So they really didn't have anything to do with the EGR's.
Then I reconnected the wires to the Danhag one by one.
It appeared the errors came from the red/yellow wire.
This is also the connection that makes the prog button flash.
So restore that connection to it's original state and no more flashing prog button.
I tried what the danhag did without it controlling the red/yellow wire.
Everything functions apart from the fact that all air seems to be directed to the foot well. Whereas with the danhag controlling the red/yellow wire, the vents are set to the position they were in when the engine was last shut off.
For now I decided to leave the red/yellow in it's factory state, i.e. not connected to the Danhag.

I just came of the phone with a tech guy from Webasto Netherlands.
I asked him about the 30 minutes maximum burning time of the fbh.
He told me that even if it was a setting in the fbh, they couldn't change it. If anyone could, it would be Land Rover they said.
I'll send a PM to collin from BlackBox. Perhaps he knows a way.

I have already left a post on BBS about a suggestion if we can edit the contents of the FBH with the FM, but up to now not had a reply.
Its gone very quiet now on this thread, this must mean we are all happy with our new GSM units and how they are preforming...
