Open Monday to Saturday · Fenton workshop
When a filter is too blocked for an on-car clean, we take it off, clean it on our workshop rig, pressure-test it and refit it, with before-and-after readings to show the flow is back.

How it works
The DPF comes off the vehicle and onto our workshop rig. We check it for cracks or a melted core first, then run a back-pressure test so you can see how blocked it is.
The rig flushes the filter with detergent and controlled heat to loosen the ash and baked-on soot that an on-car clean can’t reach, working through it in both directions until the readings are back where they should be.
Once it’s clean, we dry it, pressure-test it again to prove the flow is restored, refit it and clear the fault codes.

Step by step
Every off-car clean follows the same four steps.

We take the DPF off the vehicle and check it for cracks or a melted core.
2
A back-pressure test shows how blocked the filter is.

Why it matters
Off-car cleaning is for filters that an on-car flush and regen can’t clear. That’s usually filters packed with ash after high mileage, or ones where regenerations have failed again and again.
It removes the baked-in ash that on-car methods miss and costs much less than a new filter, which can easily run to four figures. A clear filter also keeps smoke readings under the MOT limit, and regenerations can finish on their own again.
We aim to have most off-car cleans done within one working day, though some filters take longer, so we’ll give you a time when you book. Drop-off off-car cleaning for car and van DPFs starts from £100 + VAT, and prices may vary depending on the filter, its condition and the job. Larger commercial and HGV filters are priced separately, on quote. Prices shown are starting prices. The final price depends on many factors, including the vehicle and how complex the job is, and we confirm it before any work starts.
Drop it in at our Fenton workshop, or post it to us from anywhere in the UK and we’ll send it back cleaned.
How drop-off works
1. Remove the DPF from the vehicle.
2. Drop it off at our workshop on King Street, Fenton.
3. We clean it.
4. We call you to collect it.
Garages, trade customers and fleets are welcome to drop off filters too. Larger commercial and HGV filters are priced separately, on quote.
Vehicles
Whether you remove the filter yourself or we do it, these vehicles come to us with the same problems: high soot load, warning lights, limp mode and failed regenerations.
Stop-start delivery runs clog the filter fast, and cracked pressure pipes can drop the van into limp mode.
Short commutes stall regenerations, the oil level rises and a DPF warning comes up.
Failed regenerations leave the filter packed with ash well before high mileage.
Town driving keeps exhaust temperatures low, soot builds and the car cuts power on hills.
Hours of idling on courier shifts stop regenerations, so ash and back-pressure climb.
A low DPF additive level and few motorway runs mean the filter blocks early.

How long does an off-car clean take?
We aim to have most off-car cleans done within one working day, but it can take longer depending on the filter and how blocked it is. We’ll let you know when you book.
Do you remove the DPF, or do I bring it in?
Either works. Bring the vehicle in and we’ll remove and refit the filter, or drop off or post a filter that’s already been removed.
How much does off-car DPF cleaning cost?
Drop-off off-car cleaning for car and van DPFs starts from £100 + VAT. Prices may vary depending on the filter, its condition and the job. Larger commercial and HGV filters are priced separately, on quote. Prices shown are starting prices. The final price depends on many factors, including the vehicle and how complex the job is, and we confirm it before any work starts. It’s usually much less than a new filter.
Will the vehicle pass the MOT after cleaning?
A blocked DPF can push smoke readings over the limit. Once the flow is restored, the readings come back down, so a clean is worth doing before the test if the DPF light has been on.
What if the filter is cracked or melted?
We check for damage before cleaning. If the filter is beyond saving, we’ll tell you and talk you through replacement options before going any further.
Do I need a forced regen after refitting?
Not usually. Once the flow is restored, the ECU can manage its normal regenerations. We clear the codes before the vehicle goes back to you.
Do you offer mobile DPF cleaning?
No, we no longer offer a mobile service. Every clean is done at our Fenton workshop in Stoke-on-Trent, where we can diagnose the fault and check the readings properly before and after. If you can’t get to us, you can post your DPF instead.
Call or WhatsApp us with the reg and what the car is doing, and we’ll tell you whether it needs an off-car clean.
