The diesel particulate filter (DPF) is an important component of diesel vehicles, whose main function is to capture and treat particulate matter in the exhaust. When the carbon load of DPF exceeds the normal range, it indicates that its filtration capacity has reached its limit, and corresponding measures need to be taken to reduce its burden. There are several feasible solutions here:

1. Adjust driving mode: Drive smoothly, reduce sudden acceleration, emergency braking, and speeding, as these intense operations will cause more particulate matter to accumulate in the DPF.

2. Adding fuel additives: Some fuel additives available on the market can effectively decompose carbon deposits in DPF. When using, follow the recommended guidelines of the product manufacturer.

3. Schedule regular driving schedule: Utilize the DPF system's built-in "regeneration" mechanism to burn some of the carbon deposits by continuously driving at high speeds (maintaining a speed of approximately 100-200 kilometers per hour). The specific operation details and cycles should refer to the respective vehicle manuals.

4. Seek professional maintenance services: If none of the above measures are effective, it is recommended to go to a professional auto repair shop for in-depth inspection and handling. Professionals may use more advanced equipment and technology to clean DPF. Please note that the above suggestions are only general recommendations, and the actual operation should be based on the guidance provided by your vehicle manufacturer.
