Video tutorial

In this video, we see how to reset the AdBlue warning light on a Peugeot car: there is a basic method, without tools: we insert the key and turn on the ignition; we press the accelerator all the way down for 10/15 seconds, turn off the ignition, wait a minute, and then restart.

If the warning light is still on, we must try the method with an OBD2 tool, which we will connect to the EOBD port, located at the bottom of the dashboard.

We turn on the ignition and select: "diagnosis/SCR system/AdBlue/urea counter reset", then follow the instructions and wait for confirmation. If the error persists, we must go to a workshop, because evidently something is wrong: a faulty AdBlue sensor, a clogged AdBlue injector, or the ECU needs to be reprogrammed.

In any case, do not ignore the warning light, because after a certain limit, the car will not restart, and be very careful to use only good quality urea.

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.
