Winter is Coming! But no heat!

Hi everyone, winter is coming and no heat from the car 2004 clk 320 - . Just want to ask if anyone has any solutions?

1) Constant cold air, even if I turn up the red thermostat and max it out, it still gives me cold air.

Tried:
1) Ive looked up it maybe because of the Dual Valve, a part I can replace? But it seems the w209 does not have this?

2) Diagnostic: press and hold the "Defrost" and "Recirc" buttons together, and release only when the lights on both buttons start to flash back and forth between them.
It just keeps flashing...... until I turn off the car

3) Diagnostic 2 to get error codes: http://www.benzworld.org/forums/c209...c-topic-2.html

I tried this as well, but get a ton of numbers?

Please any help will be appreciated thanks! I have this version

Just like me, the first 5-7 km without heating, after warming the engine to 90c it works finally.
I read somewhere that it might be a filter? Maybe it's normal, I did not buy a new car, I have no experience with brand new.

You won't get heat until the engine thermostat opens.
