Video tutorial

In this video tutorial, you can see how to remove the injectors in a Citroen Grand Picasso (a clean injector atomises AdBlue better and reduces exhaust fumes, optimising the operation of the DPF, thereby reducing harmful emissions). The first step is to lift the car using a lift; once you locate the injector, remove the two clips and the hidden one. After removing the clips, unscrew the mounting screw (using a V4 Allen key and a 10 mm ratchet) then open the clamp and remove the injector.

If necessary, replace the injector with a new one and reassemble all parts in reverse order (see the instructional video for assembly).

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.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
