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

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.
I often encounter this issue while driving. The exhaust self-cleaning function, to put it simply, is when your vehicle detects that the exhaust filter is clogged and needs to be parked in place to let the engine run at high speed for a while, allowing the high temperature to burn off all that soot. I drive a diesel car, so this function is absolutely crucial; if not cleared, the car won't run properly, and fuel consumption will skyrocket. You need to keep an eye on the warning light on the dashboard—once it lights up, immediately find a safe place to park, don't engage the drive gear, just put it in neutral or park, and wait for the engine to roar for about ten minutes until it automatically completes the process. Safety first—don't do this at gas stations or in garages, as the hot exhaust could pose a danger. For prevention, driving more on highways can help reduce the frequency of encountering this issue.
As a seasoned driver with decades of experience, I can explain exhaust self-cleaning in stationary mode. It means initiating the cleaning procedure while the vehicle is parked. Essentially, the car remains stationary while the engine runs at full power to burn off particulate matter in the exhaust system. When encountering this situation, I immediately pull over to handle it, as attempting regeneration while driving may interrupt the process and potentially damage the vehicle. The entire procedure is straightforward: park the car, confirm the warning light, then let the engine rev for a while to complete the process. Having experienced this multiple times, I always make sure to choose a well-ventilated location and keep people away from hot exhaust pipes. This feature is commonly found in modern vehicles, especially diesel models, and regular maintenance can help avoid such situations.
