Had to take the Z to work today.

 

Put my heater control to 40! Auto.

outside temp in Folkestone 3C trouble is my intererior never gets really warm!

 

I would have thought at that setting I should be sweating!

 

Never understand the heating controls tbh!

 

I know theres info on the controls but why is it I get very little heat?

 

Could the matrix be blocked? Its a pita to change! or thermostat? No leaks or loss of water.

 

Any ideas please

Sounds like you need the 99 spec manual heater control, do away with that digital thing :lol:, change out your thermostat would be my first port of call.

There's a pesky solenoid/valve on the heat exchanger itself that fails open or shut. Mine is open, so I get roasting heat non stop. There's other crap like a sensor in the roof that fails.
