Video tutorial

In this video, you will learn how to resolve the issue of the AdBlue and engine warning lights being illuminated simultaneously on a Peugeot 208. Additionally, the infotainment screen displays the message "pollution anomaly: starting prohibited in X miles". The additive tank is nearly full, so it is not a low tank issue.

The problem is due to the need for a firmware update, and performing a hard reset of the onboard computer did not help.

It is necessary to take the vehicle to Peugeot to have the system updated at an authorised workshop with their specific equipment.

How to Remove the Rear Seat of a Hyundai Tucson?

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.
