To replace the ECU on the Citroën C4 Picasso, open the car's bonnet to access the components inside the engine bay. On the right side of the bay, just below the windscreen, you will find the ECU. Release it from its housing by loosening the screws that secure it and disconnecting the power cables.

This will allow you to insert the new ECU, ensuring it is properly secured and connected, then check that everything is functioning.

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.
