Video tutorial

In the attached video, we can see how to remove the rear door lock of the Mercedes C-Class W203. First, we need to remove the inner door panel, then disconnect the lock connector and remove the plastic clips that hold the cable in place. Be careful not to damage the clips, as we will need to reuse them later.

Now, remove the 3 Torx screws that secure the lock using a T30 Torx wrench, and then the single screw that holds the foam piece inside the door. Now we can extract the lock unit and replace it, remembering to attach the bracket before installing it, as shown in the video.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
