To replace the engine control unit in the Ford Fiesta, open the bonnet to access the engine compartment: this will allow you to disconnect the battery and subsequently remove the cover from the top of the engine block. Once these components have been removed, access the rear of the battery, where the control unit is located, which can be freed from the connectors and fixing bolts.

This will allow you to insert the new unit, reassembling all the removed components.

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.
