Video tutorial

On the Mercedes Classe A W168, the cabin air filter is accessed from the engine compartment, in the area under the windshield. In the video, the hood is opened and the focus is immediately directed towards the long plastic cover under the windshield (the black cover near the grille), as that is where the filter door is located.

To reach it, the screws of the cover are removed with a tool, and the visible fasteners along the edge are unscrewed, then the plastic is lifted just enough to create access. With the cover raised, the point where the filter is inserted is clearly visible: at that point, it is grasped and pulled out by sliding it out of its seat.

In the video, the old filter is shown up close, and it is immediately clear why it should be replaced. After freeing the housing, the new filter is taken and inserted in the same direction, pushed in straight until it is seated correctly, ensuring it is supported properly and does not bend.

Once the replacement is finished, the under-windshield cover is closed by returning it to position, and all the screws are put back in, checking that the edges are well seated and that no gaps remain.

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.
