Video tutorial

This video shows how to resolve the issue of the engine light being on, with irregular idle and difficult starting. Even if regular maintenance is performed, deeper servicing is sometimes necessary, as exhaust gas vapours can contaminate the sensors, causing irregular engine operation, especially when cold, but also when hot - hence the irregular idle.

On a vehicle like the Citroen C3, removing and cleaning the various components is not difficult, as demonstrated by our YouTuber, and you will notice significant improvements in performance and fuel consumption. After cleaning, it will take several miles for the ECU to readapt to the new configuration, but performance will improve.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
