Why refurbish instead of clean?
Because a clean can only shift soot. Refurbishment is the full reset.
Every clean done on the car, from a forced regen to a foam treatment, leaves the mineral ash behind. Ash builds until the filter blocks again, sooner each time. Off-car refurbishment washes out soot and ash, so the filter flows like it did the day it left the factory. That’s why we can put a warranty on it that on-car cleans can’t touch.
The difference, on paper
| What you get | Regen clean | In-situ clean | Off-car refurb |
|---|---|---|---|
| Soot removed | Yes | Yes | Yes |
| Ash removed | No | No | Yes |
| Flow-test report | No | No | Before & after readings |
| Turbo checked | No | No | Yes, while the DPF is off |
| Warranty | — | Up to 6 mo / 6,000 mi | Up to 30 mo / 40,000 mi |
| Filter condition after | Same age | Same age | As-new flow |
The refurb, step by step
Diagnose & remove
Full scan first, then the filter comes off the car. If the real fault is a sensor or the turbo, you hear it now, not after paying for a clean.
Machine wash & flow-test
The unit goes through the wash rig: soot and ash out, dried, then flow-tested against as-new figures. You get the readings.
Refit & road test
Refitted with the turbo and sensors checked, regeneration verified, road-tested. Fixed price, agreed before we started.

Bring the car, or just the filter
Two ways in. Same as-new result.
Drive the car in
We remove, refurbish and refit, with the turbo checked while the filter’s off. Most jobs same-day or next-day.
Drop the unit off
Filter already off? Bring the bare unit and pay less: no removal or refit labour. Deep-cleaned, flow-tested, ready to collect with its report.
Workshops: there’s a dedicated trade service with volume pricing and fast turnaround.
Why pay £1,000+ for a new DPF?
Dealers quote four figures for a replacement filter because replacing is all they offer. A refurbished DPF flows like a new one, carries our warranty, and costs a fraction of that. If your filter is genuinely beyond saving (cracked substrate, melted core), we’ll show you the evidence and say so before you spend anything.
Refurb questions
How long does a refurbishment take?
The off-car wash, dry and flow-test take several hours, so most refurbs are same-day or next-day depending on the morning’s bookings. Bare units dropped off are usually ready to collect within the day. We confirm the honest turnaround with your quote.
Is a refurbished DPF really as good as new?
On flow, yes: the wash removes the soot and ash that were choking it, and the flow-test proves it against as-new figures before it goes back on. What refurbishment can’t fix is physical damage, a cracked or melted core. We check for that first and tell you straight if we find it.
What does the warranty cover?
Re-blocking, for up to 30 months or 40,000 miles depending on the vehicle and how it’s used. Terms are agreed in writing with your fixed quote before any work starts.
Do you do HGV, van or fleet filters?
Cars and vans, yes. For HGV and larger units, call us with the part details and we’ll confirm what the rig takes. Fleet and trade enquiries welcome.
