What does it mean to enable exhaust self-cleaning in place?

[McJuliana]

Prompting to enable exhaust self-cleaning in place means the vehicle's computer is reminding the owner to activate the exhaust self-cleaning function to remove carbon deposits from the car. The automatic exhaust cleaning, also known as the DPF self-cleaning function, can automatically or manually clean engine carbon deposits based on user needs, thereby improving vehicle power, saving fuel consumption, and being environmentally friendly. More details about enabling exhaust self-cleaning in place are as follows: 1. Main advantages: Since there is no blockage inside the DPF, the exhaust flow resistance is very low, which does not affect the normal operation of the engine. Due to the generation of soot particles, the amount of soot particles inside the DPF gradually increases, causing the exhaust resistance to rise, and the engine's fuel consumption and power are affected by the increase in exhaust back pressure.
