Quality Services
As DPF cleaning specialists, we improve the way your vehicle works, enhancing efficiency and performance and reducing emissions.
Stage One – Diagnostics
Our qualified technicians will diagnose the condition of the DPF and establish the cause of any blockages to avoid further problems.
Stage Two – Cleaning
We inject TerraClean fluid directly into the DPF, which breaks down carbon particles so that they can pass through the filter and reduce exhaust back pressure.
Stage Three – Regeneration
Starting with a one-mile drive, we reset any faults and regenerate the engine management system to ensure smooth running.
Regain Lost MPG and Performance
With more than 30 years of experience, we cover all aspects of DPF cleaning and unblocking.

What Our Customers Say
As you can see, we have countless great customer reviews for the high standard of our services:
“Absolutely Amazing”
“Absolutely amazing. Bernie sorted out one of my vehicles while we were on the job working. He kept my van and tools safe and more importantly he fixed my DPF problems in under 2 hours and the price was really good. He was so professional and very well-mannered – and may I add he did all this in the rain.”- Frank Moves Fast★★★★★“So Pleased”
“I couldn’t have hoped for better! I was desperate to get my car out of limp mode, I needed my car on the road ASAP and was worried. Local garages avoid DPF like the plague or are too busy for a week or so.I gave Bernie a ring and he came on the same day after dealing with a job near my area. He did a regeneration, and it did the job! I was so pleased, considering I was at Leeming, and he is based in Darlington. Burnie is a super nice guy, and I couldn’t thank him enough.”- Life Hunter★★★★★“A Five-Star Service”
“Bernie is extremely honest and great to chat to. Had an error code related to the DPF which was causing the car to be stuck in limp mode for well over a month. Turned out that there was no build-up of soot, but a pressure sensor that needed fixing that Bernie replaced and resolved my issue. What I loved most was Bernie's approach, which was to find out what was causing the fault and go from there. Had another garage quote me £350 to remove the filter from the car and clean it manually, when this wasn't even the fault! Think what any customer wants is honesty and that's what you'll certainly get here. If in doubt give Bernie a call as he is extremely friendly as is more than happy to answer any questions that you may have. A five-star service from me! Many thanks.”- Carlo Brancati★★★★★
