So Wife's 2022 GLE 450 has been popping this message on startup. Live in the hellhole Texas heat and the unit is functioning like new. On older models I believe you are **** out of luck and have to go to the $tealership for a reset. Does anyone know if the newer models can be reset by the owner? God I can't wait til Texas passes the "Right to Repair Act". Be interesting to see what manufacturers will be willing to give up that much market share. But lets keep that discussion on another thread.

Yup as long as you did the actual service, the reset is simple.

You just enable workshop menu and do it in the comfort of the car.

Soooooo dumb *** here was reading "AC service" not A&C service. Therein was the confusion. Thought it was HVAC related.

There are no bad questions : )
