During DPF regeneration, it usually takes 10 to 15 minutes to complete. During this period, the engine will increase its speed to raise the exhaust temperature, in order to burn particulate matter at high temperatures. If the vehicle stalls at this critical moment, the exhaust temperature cannot reach the required level, and thus cannot effectively remove particulate matter. So, if the regeneration process of vehicles with National VI emission standards is interrupted, it will indeed have an impact on the exhaust system.

If the engine accidentally stalls during the regeneration process, you only need to restart the regeneration program, which will not cause damage to the vehicle. However, if the regeneration process cannot be started or completed, such as the indicator light not lighting up properly, this may affect the normal operation of the engine and particle trap, and may even cause damage to vehicle components.

If you encounter a regeneration issue with a National VI vehicle, such as only one indicator light being on and unable to complete the regeneration process, this is usually not a serious problem. Possible reasons include damaged light bulbs or inconsistent voltage between the two indicator lights. At this point, you need to check the voltage of the regeneration lamp circuit to see if there is any damage to the bulb or if the voltage is too low.
