The EGR valve on the Clio III 1.5 dCi tends to clog with carbon, causing a loss of power and engine warning light. To clean it, remove the intake manifold and the EGR valve.

Disconnect the electrical connector and the fixing screws. Soak the EGR valve and manifold in a basin with petrol (or a specific cleaner like the one available on eBay with code 353405435745 for £11.79, free delivery) for about 15 minutes.

Use a brush to remove carbon deposits from the internal surfaces and guides. Repeat the process several times until the parts are clean.

Refit the valve and manifold, tightening the screws. Regular cleaning (every 18,000-25,000 miles) prevents clogging and extends the life of the valve.

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.
