LMM, temperature sensor or pressure switch defective?

Hello My problem is that the automatic climate control makes trouble. Sometimes it goes (meats at the beginning of the ride), then only warm air (despite climate OFF, climate has been refilled), sometimes it blows too weak or not at all. (Emission system should also leak or have a problem, but first the climate can be done, sweat) My question: Is the value of the LMM correct in idle? Can you start something with these values in the appendix regarding the error limitation? Please, thank you…
