In this video, we see a truly terrible mistake that can happen when you have a car for just a few days. This driver ran out of diesel; it shouldn't happen, but it did. The latest generation Fiat cars have the fuel filler neck designed with the "easy fuel" method, which has no apparent safety features but is completely inaccessible except at the fuel pump.

Naturally, all cars with this type of fuel tank access come with a special funnel that allows for manual refueling. Not being aware of this, the user thought it would be a good idea to pour diesel into the AdBlue filler neck, causing colossal damage, for which it may be necessary to directly replace the additive tank.

So let's be careful when refueling our car; if there are two caps, there may be a reason for it: let's think carefully.

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.
