Video tutorial

In this video, see how to easily access the EGR valve of the Citroen Jumper (also applicable to the Fiat Ducato or Peugeot Boxer, as the procedure is essentially the same). To do a proper job, you must also remove and clean the electronic module, which is equally dirty and needs to be cleaned.

The method recommended by our YouTuber, which will restore the parts to near new condition as shown in the video, is to soak them for at least three days in a suitable product. We recommend the Arexons EGR valve cleaner if you prefer a spray, available on Amazon with code B01FY0IDDQ, priced at £14.00 including delivery.

If you prefer a liquid product, we suggest Bardahl, which costs £21.16 including delivery, also on Amazon with code B019J2ACA2.

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. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
