While not sharing the opinion of the understandably frustrated user, who is likely fed up with the recurring warning of a faulty AdBlue system in their Peugeot 3008 - despite having a full urea tank - the fault mode, which likely starts from the feed pump, can also be caused by poor quality fluid.

Unfortunately, AdBlue is urea-based, a natural product that used to come 90% from Ukraine, whose current situation we all know.

Therefore, the product currently available may not be of high quality, which certainly affects the operation of the sensors that were calibrated for a specific type of product that may no longer exist. This is not a consolation for those in trouble like our YouTuber, but it may help to understand.

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.
