The procedure described in the video is an extreme emergency measure that may cause damage to the vehicle. However, if you find yourself on the road with family and don’t know how to reach the nearest fuel station, you must find a way to manage (but we should have thought of this earlier!). When the AdBlue runs out, our Dacia Duster enters protection mode, and if we are driving, the engine power is drastically limited until the car shuts down and cannot be restarted.

The YouTuber disables the start & stop system and then starts the car by pushing it (in second gear, with the key in the ON position, releasing the clutch sharply while the car is moving). This tricks the ECU and starts the engine mechanically, bypassing the electronic lock.

The risk is that the engine, running without AdBlue, will cause a spike in NOx emissions, damaging the catalytic converter and the particulate filter; furthermore, even if the car starts, it is highly likely that the ECU will soon limit the revs and power again.

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.
