This has the remote operation Webasto fitted.
On operation of the remote the Webasto fires up and after 30 seconds or so the cabin blower starts to run.
The problem is no hot air just cold.
There is a double water valve fitted just under the webasto.Hot water in but not hot water out.
Three pin plug shows 1.8 volts.(?)
I have found a general schematic but dont understand what voltage I should be getting and where it comes from.
I have a load of BMW fault codes that I am trying to figure out!
Dont work on many BM`s so any help appreciated.
Thansk,
Tony
