5 Warning Signs Your DPF Needs Professional Regeneration

Think something's off with your diesel car?

Maybe it's lacking power, using more fuel, or that DPF warning light is staring you in the face. It could be your Diesel Particulate Filter (DPF) telling you it's time for a clean.

Your DPF is designed to trap harmful soot from your exhaust, preventing it from polluting the air. Over time, this filter can get clogged, impacting your car's performance and the environment.

Luckily, there's a process called DPF regeneration that burns off this built-up soot.

What is DPF Regeneration?
Basically, your car increases the exhaust temperature to burn off the accumulated soot. This can happen passively during highway driving or actively when your car's system initiates the process.
How to Tell if Your DPF Needs a Professional Clean
Here are some signs your DPF might need some professional attention:
  • Warning Light: That DPF warning light on your dashboard? It’s best not to ignore it.
  • Reduced Power: A clogged DPF can restrict exhaust flow, making your car feel sluggish and underpowered.
  • Increased Fuel Consumption: If you're filling up more often, a blocked DPF could be forcing your engine to work harder and use more fuel.
  • Unusual Smells: A burning smell could indicate your DPF is overheating.
  • Frequent Regeneration: If your car's DPF regeneration cycles are happening more often, it's struggling to clear the soot on its own.
