Hi, my first post on this forum.
I have a RRS SVR 2015 and having issues with the heating. The car is only blowing cold air. The vehicle doesn’t lose coolant. It doesn’t over heat even on a long drive.
I have changed the pump on the side of the fuel burner heater and the water valve underneath and still doesn’t make a difference.
Then you feel the pipes going to the heating matrix on the bulkhead, they are both cold. The pipes coming in/out of the fuel burning heater are also cold regardless of the car has been run for an hour.

Obviously we are desperate to get the issue fixed. Can anyone advise or point us in the right direction.

Any help is appreciated.
