I did some data logging which I will try to post once I get back.

My cars AC causes about 10 newton meters of drag torque to the engine when on coldest. (I will compare it to the engine torque produced later)

In car display says 0.7-0.8 liters of diesel per hour.

It reports this value even when the car is in dfco mode. And it appears to be a pre estimated value.

Car is audi a3 1.6 tdi 2012 with 200k km.
