The engine warning light is on and the loss of power in a Volkswagen Polo can indicate a malfunction of the EGR valve, the spark plugs, or the engine itself. In the case of the following video tutorial, the loss of power and the engine warning light indicate a failure of the turbocharger.

In fact, the housing of the turbocharger, which contains a fan inside, has been completely destroyed due to lack of checks and maintenance. The breakage of the fan leads to complications for the engine since the lack of airflow overheats the engine, causing it to lose power.

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.
