You need to have a red wire from pin 2 of the 8 pin connector on the FBH, then you can just use crocodile clips to connect to the pins on the OBD cable (one to the red fbh, +12v, -ve) and the WTT software your laptop Thumbs Up

You need one of the diagnostic looms from the site shop AND the USB/OBD2 adapter from eBay.

Or home-brew a loom for yourself if you have the bits Smile

CO2 adjustment not working on Thermo Test Software

Hi group,

I need your help on the following matter: These days I started working on fixing my webasto for my discovery 3, 2006. It was starting but turning off by itself in 30 sec. Thanks to this forum I managed to clean it, diagnose it and make it run. It has the 02h error. Blow on it and made it run. Still if I don't blow on it, it will stop.

So I tried the sugested aproach to increase the CO2 setting from Calibration => CO2 adjustment. Still, when the adjustment window opens I get the following error:

CO2 adjustment is not possible! The heating unit is not within the necessary operating state or adjustment value out of the valid range.

I have no other option but to close this window.
I used:
- Thermo Test software installer v2.14
- Thermo Test software installer v2.16.1
- Thermo Test software installer v3.4
Same error on all. VCDS pin configuration: 4, 7, 16. I think now that I never tried using pin 5 as ground instead of 4.

Do you have any suggestions for me?

As I see I have 2 options:
- increase the setting as you all did - but need your help to pass the error.
- mount a 12V fan to continously blow into the air inlet.

Many thanks!

I have just encountered the same thing…
To adjust the CO2 level, the unit has to be running so start it from the software in ‘Parking Heater’ mode and once it’s up and running you should be able to access the CO2 adjustment.

Good luck

Thank you Bizbauer!

I tried again today, with my improvised fan blowing and I left it run for about 10 mins. After that I was able to enter and edit the CO2 setting. Of course, while still running in "Parking Heater" mode.

I modified the value to something close to the maximum (last value before the maximum) and since then I tried 2 time without any blower help and seems to work perfectly.

Regards,
Ionut
