I was playing with the climate control unit and by chance while keeping REST button pressed for some amount of time (like 5 seconds or more) while the engine was running, some data appeared where the temperature usually appears. I was able to scroll through several values with the AUTO buttons. I have looked online to find out what exactly they show but haven't found any good source. Anyone has any information??
Your guess is correct. The link below will take you to a site that has a pfd of the MB fault code readouts and procedures. Scroll down to p95 for the W210 AC Fault Codes. You may have to copy and paste the URL to gt it to work correctly.
