Most diesel cars and vehicles have a DPF that comes with it to improve the vehicle’s performance. However, with a lack of awareness about DPF maintenance and filters, your vehicle could get affected.

Since the filter essentially keeps the soot burned off which releases harmful chemicals while also affecting the engine, maintaining it is essential. Neglecting this can cause long-term repercussions that can prove costly for every car owner.

With this, keeping yourself informed about what the filter is and how it works can help you properly maintain your vehicle and keep it in the best condition and we’re here to help you with that. Since car security systems like car alarms and immobilisers are something everyone usually focuses on, processes like engine remapping or ECU tuning and DPF maintenance may take a backseat.

That said, we’ve put together a short guide on all you need to know about DPF filters and maintenance so that you can keep your vehicle in the best condition at all times.

So without further ado, let’s take a look!

What Is A DPF Filter?

A diesel particulate filter or DPF acts as a sieve that catches all the soot particles from the exhaust. With this, the CO2 and other harmful emissions of your vehicle are reduced.

However, since the DPF filters have a limited capacity, the soot may get too much proving the filters to be ineffective. This means that you need to stay on top of maintenance to prevent this from happening.

To regenerate properly, the filter needs to be taken out and cleaned to burn off the soot effectively. If regeneration doesn’t happen effectively, it could damage your vehicle and prove to be expensive in the long run.

How Does A DPF Filter Work For Your Vehicle?

Responsible for capturing the soot emanating from your vehicle, DPF is a must-have for all diesel vehicles. While most of them already come with one attached, in case your vehicle doesn’t have one, you should definitely consider adding one in to improve the vehicle’s performance and save you from unexpected costs in the future. Since DPF burns off the soot at a high temperature, there’s residual ash that is left behind. This is known as regeneration.

With DPF regeneration occurring every 300 miles, ensuring you’re on top of maintenance will only work out in your favour. That said, there are 2 types of regeneration that occurs –

  • Passive regeneration: When your car runs at top speed on a long road, this results in the exhaust temperature rising and burns off the excess soot captured. This is when passive regeneration occurs.
  • Active regeneration: With this type of regeneration, extra fuel is added to your vehicle which makes the most of your ECU. When the DPF filter reaches the exhaust limit, the filter can be reprogrammed to increase the temperature and burn off the extra soot.

Ways To Maintain Your DPF

While DPF filters require taking care of, people may consider removing them. However, this is a bad move and something you should definitely avoid. This may be a cheaper option for temporary times but can bring up several costs in the future.

When it comes to cleaning up a blocked filter, going for a 40-minute drive is a sure-shot way of keeping your DPF clean at all times. Another thing you can consider doing is keeping your fuel tank full. Some vehicles don’t regenerate even on the highway simply because your fuel is low.

Additionally, you should always use manufacturer recommended oil as using the wrong one can potentially damage your vehicle.

To Sum Up

Driving a vehicle without having a DPF filter is illegal and making sure you have one is essential. From reduced emissions to incorporating a green lifestyle, these filters have various benefits that they bring to your vehicle.

All you need to do on your end is to keep your filters in good condition at all times and see the noticeable difference in your vehicle!
