Do I have to change my diesel particulate filter?

Owners often are not sure of what it means to be “DPF-fitted” diesel.

A filter for the exhaust which is installed on the majority of modern diesel cars is known as DPF.

It is used to eliminate harmful gases like hydrocarbons and lubricants out of the fuel and lubricants, and water as well as Sulphates, which bind to soot and create harmful particles in exhaust fumes from diesel engines.

These dangerous gases could result from a range of causes, such as inadequate maintenance or fuel quality, as well as bad driving habits that lead to poor combustion.

The particles are absorbed by the DPF filter and later cleaned or recycled through high-temperature combustion. Problems may arise in the event that regeneration has not been complete and the filter gets blocked, or your DPF gaskets don’t work properly.

I’ve observed diesel’s particulate filter described as a costly and complex component that needs to be replaced. However, this is not the case to my knowledge. It is possible to avoid replacement If it is controlled, diagnosed, and properly maintained.

A DPF error in the engine’s computer doesn’t necessarily indicate that the DPF is blocked.

What are the symptoms of obstruction of DPF

The following symptoms could be observed in the event that your DPF is blocked or requires maintenance.

  • Surging/poor performance.
  • Excessive fuel consumption.
  • Smoke Excessive – Blue, White, and black
  • Display of the engine or DPF emission light
  • It is difficult to start the engine
  • The engine is running rough
  • Unfeasible attempts to regenerate

What is Regeneration?

The computer in the vehicle’s embedded algorithms runs periodic renewals (burns). It is a procedure where the system increases the temperature of the exhaust, and then burns off any particles that are built up within the filter.

If a component is unable to function correctly it could cause a surge in the frequency of regenerations, or even end them all together until the issue is resolved. Smoke that is black and excessively released in the exhaust following regeneration. It’s normal and is not a risk. If smoke is constantly blowing this indicates that there is a root issue and urgent attention is needed.

What are you able to do to minimize the chance of DPF blockage or failure?

  • Make sure that the mechanic you hire is experienced and knowledgeable in diesel engines
  • Beware of oil misplaced or not used
  • Beware of driving while you have an issue in your vehicle (dash warning light)
  • Do not use diesel that is of poor quality
  • Modify your car with the attention

I have to deal with driving behaviors that result in DPF to reduce idle time, and increase the rpm when I am driving (dropping down the car) particularly when traffic is crawling.

The mechanic you hire should be able to detect any changes to your vehicle, for example, more raucous whistles or hissing sounds when driving. Your DPF might not be able to regenerate because of unusual driving habits. If your mechanic recommends that you do them, don’t use “on-vehicle intake/induction cleansings“.

They could result in damage to DPF’s and other components that are important. Diesel Help Australia can provide the mechanic with an explanation about the reasons why you shouldn’t employ this method. Components that fail and cause DPF problems do not always indicate that the DPF has to be replaced. Maintained DPF can travel as far as 200 000 km before it needs to be taken off to clean or replace.

What’s the price for cleaning or replacing the DPF?

  • Be conscious that DPF work should be performed by a certified skilled mechanic with the proper tools to reset and re-fit the DPF.
  • Once the fault has been verified after which the DPF must be either cleaned or removed with the DPF cleaning service.
  • Five years of cleaning experience is a requirement for a reputable DPF cleaning business. It is also possible to determine whether the DPF is damaged internally.
  • A mechanic will examine the DPF on your car to determine if it’s blocked. They are not able to determine whether or not the DPF has collapsed or melted internally, causing the blockage.
  • The average cost of cleaning an automobile for a person is $600.
  • A variety of vehicles are able to be equipped with DPF’s.
  • Manufacturers alter their designs often and it is difficult to determine whether the DPF model works with a specific automobile model.
  • Since the DPF is the most tightly controlled component in motor vehicles, it will not disclose who the DPF manufacturer could be.
