A Note on DPF Regeneration

Like most other filters in vehicles, sometimes you need to clean the filter and burn of accumulated soot. However, what makes the DPF filter different from the rest is the regeneration process that the filter initiates. Automatically enacted, the process occurs while the vehicle is in motion between every 2,000-10,000 km and takes anywhere between 30-60 minutes once the engine heats up to a proper operating temperature. There will be a green light that indicates the process is ongoing and it can even be paused should you stop driving and turn off the vehicle; it will resume when you resume driving, giving you maximum comfort and convenience while driving with minimal to no interruptions at all.

Common causes why DPF warning light pops-up

  • A Failing Filter– Sometimes the DPF light turning on is an indication that your Diesel Particulate Filter has failed or is partially blocked by a buildup of excess soot that needs to be burned off. By regenerating or burning off the soot from the filter, you may begin to notice a hot smell from the exhaust while your fuel consumption will increase while it is burning off.
  • If The Soot is not Burned Off– Should you ignore the indicator light and continue driving as normal, you will begin to notice a fast deterioration in your oil’s quality if the soot is not burned off. Make sure to check that your oil level is not above the maximum level as this can lead to extensive damages to your engine.
  • DPF Light is On Steadily– If your DPF light is constantly illuminated then it likely means that it needs regeneration. If this is the case then you likely can continue driving for several more hours before the engine begins to experience any troubles but it is best to have the DPF filter regenerated immediately to avoid any issues should the light come on.
  • DPF Light is Flashing– If the light is flashing this is a much more important and urgent warning, it indicates that a parked regeneration is required and will need to be taken care of as soon as possible. It is also possible that you will hear a beeping sound that is meant to alert you to perform a parked regeneration. This can take anywhere from 20-40 minutes to complete so get to an area where it is safe to stop and perform the parked regeneration before further damages can be inflicted to the performance or components of your vehicle.

Some more words on DPF

Mercedes Benz is known for a variety of innovations and advancements that help them maintain their status as the premiere luxury vehicle. The Diesel Particulate Filter not only leads to cleaner emissions but its’ self-regeneration capabilities maximize the ease and comfort for the driver, improving the driving experience from start to bottom. If the DPF light comes on in your Mercedes, it is important to know what it signifies but also even more than that, it is important to know what may be damaged should the light be ignored or should you continue driving as usual, putting added strain on the engine and hindering your vehicle’s performance and your enjoyment.
