This 1999 Mercedes E-Class has an air conditioning issue. The climate control button (likely the "Eco" or A/C button) remained pressed (thus on) and did not respond to commands; as a result, the air conditioning did not work.

A low refrigerant charge was identified, so the system was recharged, but the solution was not effective and the system did not start working again. A diagnostic scanner was then connected to the vehicle, and the stored error codes in the control unit, caused by the previous low gas pressure, were cleared.

After clearing the codes, the button started functioning correctly, and the air conditioning system works properly.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
