To replace the fuel filter on a Ford Focus Mk4, park the vehicle on a flat surface, turn off the engine, and open the bonnet. Locate the fuel filter in the engine bay or in the area specified for the diesel engine.

Place a cloth or container under the filter to catch any fuel spills. Carefully disconnect the electrical connectors and fuel lines, then remove the fasteners holding the filter in its bracket.

Extract the used filter and install the new one, ensuring it is fitted in the correct orientation as indicated by the manufacturer. Reconnect the fuel lines, electrical connector, and fasteners.

Before starting the engine, perform the priming procedure specified for the vehicle to fill the new fuel filter and eliminate air from the system. Finally, start the engine and check for any leaks around the filter area.

How to Activate the Disabled TRC on the Toyota Yaris?

As the video clearly shows, disabling or activating the traction control (TRC or ESP) on the Toyota Yaris is very simple. By default, the traction system activates every time the vehicle is started. To disable it, simply press the button depicting a skidding car located in the centre of the vehicle where the controls are, such as the hazard lights and the radio, but near the handbrake. Once disabled, the TRC off light will illuminate on the dashboard. To reactivate it, just press the same button again.
