In this video, we see how to diagnose and then clear the control codes on the Mercedes S-Class W220 version: to do this, we will have to open the diagnostic menu by pressing the call filter button and the "Rest" button simultaneously for about five seconds.

A message will appear on the display telling us that the system is searching for error codes; to switch from one number to another, we will have to raise the passenger climate control button.

To clear the error codes, we will use the "auto" button, pressing it from both sides, and then the display will tell us that we have cleared them.

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.
