[Thermo Top V Wbus analog is not working. just blowing air]

Hi!

Im new on this forum. I bought myself a Thermo top V couple of months ago. 
So, as the title says, i have a Webasto problem. The webasto is comming from a touran Diesel.

I bought a loom, 12v diesel pump and a wbus to analog. I tried to start it but now its just blowing air.

sometimes the waterpump starts kicking on but nothing more.

 

i will go to a company to read the webasto on a computer but i rather fix it myself!

 

i made a video on youtube
