Carbon Cleaning DPF

Over time, your vehicle’s exhaust and engine components can accumulate dirt, grime, and particulates, which not only reduce performance but also increase wear and tear. One part particularly prone to this build-up is the Diesel Particulate Filter (DPF).

The DPF is a key component in diesel vehicles, designed to capture and filter out harmful soot and particulate matter from the exhaust gases—helping meet strict European emission standards. However, without regular maintenance, the DPF can become clogged, leading to reduced efficiency, increased emissions, and potential engine issues. That’s why DPF cleaning is essential—it helps restore performance, improve fuel efficiency, and extend the life of your vehicle.

DKU DPF solution is as follows :

  • First, we manually remove the DPF from your exhaust
  • Then, we carefully split open the DPF unit to access the filters
  • Soak the DPF filter in cleaning chemicals
  • Reassemble the DPF unit and reinstall in your vehicle

dPF regeneration and hydro-clean

  • We can also perform manual DPF regenerations with Hydrocarbon Cleaning services to improve the performance of your DPF unit.
  • While your vehicle regenerates the DPF, our carbon cleaning services remove any other impurities in your vehicle.

dKU performance can help you clean up your dPF for cleaner exhausts!

As of February 2014, UK MOT regulations require that any vehicle originally fitted with a Diesel Particulate Filter (DPF) must still have it in place and in working condition. It’s actually an offence under the Road Vehicles (Construction and Use) Regulations to drive a car that’s been modified in a way that compromises its original emissions standards.

Failing to comply can lead to serious penalties—up to £1,000 for cars and £2,500 for light goods vehicles. Avoid the risk (and the fine) by keeping your DPF well-maintained. At DKU Performance, we offer professional DPF cleaning, regeneration, and replacement services to keep your vehicle compliant, efficient, and running at its best.

How can I get my DPF working properly again?

If you’ve noticed any signs of a faulty DPF, don’t ignore them—get expert advice and sort it out before it ends up costing you in performance, repairs, or fines. Once your DPF warning light comes on, the filter is already heavily blocked, and you’ll typically be left with these options:

  • DPF Regeneration: We can help regenerate your DPF by burning off the built-up residue and soot in a controlled environment.
  • DPF Cleaning: By removing the DPF unit, giving it a deep clean and replacing it, we can remove almost all the particulates that were clogging up your filter.
  • DPF Replacement: A quick DPF replacement will give your exhaust system new life.

If you’re still uncertain of which service would be best for your DPF needs, please contact a member of the DKU team for advice, guidance or to arrange a visit to our garage.

common misconceptions:

Cleaning a DPF can be complex, so don’t be fooled by quick fixes or shortcuts. The only reliable way to restore your DPF is through professional repairs and reconditioning. Below, we’ve debunked some common myths to help clear things up:

  • Going for a blast’ can clean your DPF: While passive regeneration happens at high speeds, this isn’t enough to properly clean your DPF and can even damage your vehicle
  • Putting DPF cleaning additives in my car will clean the unit:
While there are many additives on the market which can help your engine health, there is still no substitute for thorough DPF cleaning or regeneration
