Can You Continue Driving with a DPF Regeneration Fault?

[DeNadia]

You can continue driving with a DPF regeneration fault. Here are the precautions for DPF usage: 1. Fuel requirements for the DPF post-processor: It is necessary to use low-sulfur diesel that meets China V emission regulations (sulfur content less than 10ppm) to prevent poisoning and clogging of the post-processor. Additionally, to extend the cleaning interval of the post-processor, it is recommended to use CJ-4 grade or higher engine oil. The ash content in the lubricating oil can significantly affect the DPF, as high ash content can easily cause DPF clogging. 2. Conditions for triggering DPF regeneration: Regeneration is triggered by carbon loading, which is calculated through the ECU's internal data model. When the carbon load is between 18g and 30g, active regeneration is used, where the engine operates normally, the exhaust treatment system outlet temperature is higher than the normal range, and the high exhaust temperature light remains on. When the carbon load is between 30g and 40g, driver-initiated regeneration is used, meaning manual regeneration by the driver.
