I am having problems with my auxiliary heater, it starts but does not but only runs fore 5 minutes then turns of, I have put in a new webasto, but have the same problem with the new one. I'm trying to code it, but there is one code it wont let me put in. Co2 setting (cold setting of combustion air blower), when I try to code in the new setting I get : Comunication error 8.561.6067.
is there a way to get around this error
