In this video tutorial, see how to replace the diesel filter on Alfa Romeo 159 by following these simple steps: first, purchase a new diesel filter; next, get inside the vehicle, turn off the engine, and pull the handbrake. Lift the bonnet and secure it with the prop rod. Squeeze the sides of the diesel pipe and pull upwards to disconnect it; mark the pipes to remember where they go during reassembly.

Using a 10 mm socket, unscrew the bolt holding the diesel filter bracket counterclockwise (continue unscrewing by hand to avoid dropping it into the engine bay). Remove the bracket, lift the filter, and underneath you will find the sensor; gently press with your fingers to disconnect the cable and remove the sensor.

Position the new diesel filter and reassemble all parts in reverse order.

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.
