DPF Specialists based in Newport

A Diesel Particulate Filter (DPF) is a critical component in modern diesel vehicles, designed to trap and remove harmful soot and particulate matter from exhaust gases. Over time, these filters can become blocked due to short journeys, poor maintenance, or issues with the regeneration process.

Common DPF Issues

When a DPF becomes clogged, it can lead to a range of problems including reduced engine performance, increased fuel consumption, dashboard warning lights, and even limp mode. At Hill Vehicle Services, we specialise in diagnosing, cleaning, and restoring DPF systems to keep your vehicle running smoothly and efficiently.

Our Comprehensive

DPF Solutions Process

01

Initial Assessment

We begin with a thorough diagnostic check using genuine main dealer tools to assess your vehicle’s DPF system. This helps us identify any faults, blockage levels, or underlying issues such as failed sensors or incomplete regenerations.

02

Professional DPF Cleaning

If the DPF is blocked but still in good condition, we carry out a specialist cleaning process to remove soot, and contaminants. Our method restores optimal flow and performance without the need for removal, helping to reduce emissions and improve fuel economy.

03

Final Road Test

After cleaning, we reset the relevant system data, carry out post-clean diagnostics, and complete a road test to ensure everything is functioning as it should. We only return the vehicle once we’re confident the DPF system is fully operational and road-ready.

Highly recommend friendly & extremely helpful. My car was taken in for diagnostics and repaired the same day, I was expecting it to be a big / expensive problem but this garage was extremely thorough & honest and ended up costing a lot less that I expected.

Sophie. D

Mike found the root cause of the issue and there was no problem with the filter itself. Mike rectified the issue and I collected my car the next day, amazing service and great people!!

Judith. S

What a great company, when I called them my car had previously been misdiagnosed at a different garage at a significant cost, when I spoke to Mike he asked me a lot of questions, and I dropped my car at a easy location, he had the car for a few hours and I had a full assessment report and he talked me through what was required, later that day my car was ready for collection dash light free!! Would highly recommend

Frequently Asked Questions About DPF Issues

What is a DPF, and why is it important?

A Diesel Particulate Filter (DPF) is a crucial component in modern diesel vehicles that captures and stores soot from exhaust gases to reduce harmful emissions. Keeping it clean and functioning properly is essential for your vehicle’s performance, fuel efficiency, and compliance with emissions regulations.

What are the signs of a blocked or faulty DPF?

Common symptoms include loss of power, increased fuel consumption, frequent regeneration cycles, engine warning lights, or the vehicle going into limp mode. If you notice any of these, it's best to get a professional DPF inspection as soon as possible.

Can a DPF be cleaned instead of replaced?

Yes. In many cases, a professional DPF clean can restore your filter to near-original condition, saving you the cost of a full replacement. Our advanced cleaning methods effectively remove built-up soot  helping extend the life of your DPF.

How long does a DPF clean take?

The duration can vary depending on the level of blockage and the vehicle type, but most DPF cleaning services are completed within a few hours. We aim to get you back on the road the same day whenever possible.
