V50 Error Ventilation System (Interior) CCM – 0070

Moin moin, I have been having problems with my air conditioning/ventilation system for quite some time, not really warm in winter and not cold in the “summer”. I have added a few current screenshots from VIDA. Main error code CCM 0070. I tried to start a calibration with Vida several times. I had to stop once, because after the status had not changed after 10 min, the next attempt ran through but the problem has now rather strengthened. Now it is so that I get on the driver side, regardless of the desired temperature setting, sauna feeling and the passenger at the lowest temperature setting minimally a lukewarm breeze but nothing cold arrives. Do your experience or advice about the problem (VIDA DICE is available)? Thank you in advance!
