Heating not working
Hi I have a 2005 e320. The internal heating seems not to be working and seems to be intermittent I have checked the coolant bottle which was a little low and have topped it up. Which I thought had worked as the heating got hot but has now gone back to just blowing cold is there anything thing else I can check or do before bringing it into a garage

Might be the heater control valve, they are notorious for failing. Could also be a temperature sensor(s)
