DPF Services

A blocked DPF makes a diesel feel flat, burn more fuel and light up the dash, and a new filter is an expensive way to fix it. A DPF doesn't need replacing after a set number of years. At JTK Remapping in Dungarvan, Co. Waterford, we take the filter off, clean it on our custom-built DPF cleaner and refit it, for a fraction of the cost of a replacement.

Why a DPF blocks

Most diesel cars built since 2009 have a diesel particulate filter (DPF), which traps the soot in the exhaust. The filter clears itself by burning that soot off, which is called regeneration, and it needs a good long run to do it. If most of your driving is short trips, it never gets the chance, the soot builds up and the filter blocks.

Signs your DPF is blocked

  • Less power than usual
  • Higher fuel consumption
  • A DPF or engine warning light on the dash

If you're not sure the DPF is to blame, our vehicle diagnostics will find the fault first.

Cleaning instead of replacing

Kept in a state where your car's ECU can regenerate it, a DPF can last the lifetime of the car. Our cleaning brings the filter back to that state, and we guarantee a cleaned filter lasts as long as a replacement would.

What happens when you bring it in

Bring the car to our workshop and we take the DPF off, clean it on our DPF cleaner, refit it and test the car to make sure everything is working as it should. If it suits you better, send us the DPF on its own and we'll clean it and send it back to you. If the car is due a service, ask about general maintenance on the same visit.

DPF removal

We also carry out DPF removal. If you ask us to remove a DPF, it's your responsibility to check that it's allowed for how and where the vehicle is used, and to tell your insurer, as our terms and conditions set out.

DPF questions

Do I need to replace my DPF after a certain number of years?

No. A DPF that your car can still regenerate can last the lifetime of the car. When it blocks, cleaning it brings it back, and we guarantee the same lifespan as a replacement.

Can I send you my DPF instead of the car?

Yes. Send us the filter and we'll clean it and send it back, ready to refit.

Ring us on 087 744 2633 to book the car in or to arrange sending your DPF. You'll find us on the Youghal Road in Dungarvan, with directions on our contact page.
