What is the solution when a Land Rover displays that the exhaust filter is full?

Land Rover displays that the exhaust filter is full. The solution is to clean the three-way catalytic converter. The three-way catalytic converter can convert harmful gases such as CO, HC, and NOx emitted from the vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. It has relatively stable performance and reliable quality. Land Rover's automotive brands include: Discovery, Range Rover Sport PHEV, Range Rover Velar, Defender, and Range Rover Evoque (imported). Taking the Discovery as an example: this vehicle is classified as a mid-to-large-size SUV, equipped with a 2.0TL4 engine, featuring turbocharged intake, with a maximum horsepower of 300ps and a maximum torque of 400nm.
When my Land Rover displayed the 'exhaust filter full' warning, I was initially a bit panicked, but later followed the advice from online car enthusiasts to drive on the highway to resolve it. The exhaust filter is a device that captures diesel exhaust gases, and when full, it may affect engine power. I tried driving on the highway, maintaining a speed of 100 km/h for half an hour to let the engine work at high RPMs and burn off the accumulated particles. This method is called passive regeneration, and it was quite effective. However, it's important to ensure a safe driving environment and stable speed. After the highway run, the warning light went off, indicating the issue was resolved; if it didn't, a professional check would be needed. There, they have equipment to manually initiate an active regeneration program or check for hardware faults. Timely action is crucial, otherwise it could increase fuel consumption or damage engine components. I've now developed a habit of regular checks to avoid recurring carbon buildup issues from short trips.
