Hello, the following problem: there m111.957 2.0 compressor. In the car is very cold (-20 outside) at a temperature of 80 degrees engine, climate control shows the temperature of the heat exchanger left / right 25 and 27 (in diagnostic mode climate control)
I checked:
1 main pump, all right.
2 solenoid valves, they work.
3 Electropomp working.
4 blew heater exchanger radiator. It clean
5 cabin filter removed under the glove compartment.
The water feed pipe on the heater exchanger warm.
Can be a problem in antifreeze tank cover?

-20F or -20C? At any rate there's a practical limit on just how much really cold air a very small engine can warm up. Once a had a 1.6l MG. I would let it idle with the heater on for 10-15min. Inside would be really warm until I started driving down the road. In just a few minutes the air coming out of the heater would be barely warm. Cars for cold climates used to be offered with optional electric heaters but now maybe only trucks have that option.

FYI heated coolant comes from the back of the block to the bottom of the heater core and exits the core at two places into the duovalve, with a single exit to the bottom of the coolant pump------I suspect that the duo valve is staying closed(based on you numbers)and not allowing hot coolant to flow/exit the heater core ---therefore cabin is cold.

I would make sure that your dials are turned way over to red therefore telling the duo valve to stay open---I would also do a fault check on the AC unit--any faults
