I can usually find a good temperature if I finely balance the nob at around the 16c mark but any other position their is either no heat or gas mark 100. When going down the motorway though it seems fine until I slow down again. Anyone have any suggestions or should I just stop complaining?

Does your engine take a while to warm up?

It does take awhile but keeps temperature fine after I changed the thermostat. I assumed that was normal with these sdi engines though?

Ok, the heater flap motor must be playing up.

Easy fix? Does seem strange to me that it works when moving fast though and I can get a normal range of temperatures out of it.

 

Is the temperature supposed to be electronically regulated? i.e. when set to 20c on the nob it will regulate the cabin temperature to 20c?

It is supposed to work that way, yes, perhaps the cabin thermostat is blocked, there's a little grille with a tiny fan behind it.

Yeah, clean any dust from this little grille....
