In this video, we demonstrate a method to clean the AdBlue injector, which in this case is located on a Peugeot 308, but the system is applicable to any vehicle fitted with this additive system. The injector is located at the bottom of the vehicle and is not difficult to remove: simply take off the clip, and you will have the injector on one side and the seat on the other.

In this case, the YouTuber cleans it with a wire brush, and the result is certainly good. However, we recommend an even simpler method: immerse the injector in very hot water and clean the seat with a cloth soaked in the same hot water.

This will remove all dirt and AdBlue deposits in no time, making it practically new. Ensure it is thoroughly dried before refitting the clip.

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.
