In this video, we see how to reset the DPF error light on a Hyundai Tucson (or a Kia Sportage): when the warning light appears, it means that the DPF is almost blocked, and the car needs to complete a cycle of active regeneration, which requires specific conditions to start, and which we can create in this way: drive the vehicle over 60 km/h, ideally on a rural road, maintaining a high gear, and with the engine speed between 1500 and 2000 rpm. We will need to drive in these conditions for at least 15/20 minutes, during which the engine management system will automatically activate the regeneration.

The warning light will disappear from the dashboard on its own once the cycle has been successfully completed.

It is very important not to ignore the warning, and not to turn off the engine if regeneration is suspected to be in progress.
