DPF Cleaning & Regeneration

DPF Cleaning & Regeneration
While You Wait

Remove soot, restore flow, and drive with confidence.

Don’t let a blocked DPF ruin your day. Pull into our Hanley workshop and we’ll run a dealer-grade diagnostic, flush the filter with a three-stage clean, then trigger a safe forced regen. Watch soot and back-pressure drop on the screen and see the warning lamp clear—all in under an hour.

Why Drivers Book Us

Cleaner Exhaust,

Smoother Drive

We help drivers beat limp mode, regen failure, and engine faults with our in-house DPF Cleaning & Regeneration service. A three-stage chemical flush and controlled regen clear soot and ash on-car, saving you the cost of a replacement filter. Watch the before-and-after back-pressure readings on our scanner—then drive away in under an hour.

A blocked DPF builds back-pressure that starves the turbo of airflow and forces the engine to work harder for every mile. In our Hanley workshop we run a three-stage chemical flush that dissolves compacted soot, then use a controlled forced regeneration to burn off what remains at the right temperature. With flow restored, exhaust gases exit freely, throttle response sharpens, and many drivers notice a lighter feel in the lower gears plus better fuel economy on the very next fill-up.

When passive regens fail, soot loads climb fast. Rising pressure strains temperature sensors, turbo seals and injector tips, and limp mode soon follows. Short trips only speed up the spiral. Cleaning the filter before it reaches the danger zone stops that snowball effect. Live data on our scanner shows soot mass and back-pressure (kPa) dropping in real time, proving the system can now protect itself through normal driving rather than emergency measures.

A healthy DPF is essential for low emissions and an MOT pass. Excess soot can push smoke opacity over the legal limit and trigger an instant fail; tampering or deleting the filter risks fines and void insurance. Our in-house clean restores the factory filtration rate, clears stored faults, and resets adaptation values so you can roll into the test lane with confidence—without paying for a new filter.

Common DPF Call-Outs

Vehicles We Clean Most

for Blocked DPFs

Some makes and engines clog their diesel particulate filters faster than others, especially on short urban runs where the exhaust never gets hot enough for a passive regen. Below are the cars and vans we’re called to every week for DPF cleaning and forced regeneration.

Ford Transit 2.2 TDCi

Delivery routes and constant idling load the filter quickly; split pressure-sensor hoses make the ECU think it’s even fuller.

BMW 320d / 520d (N47)

Short commutes interrupt active regens, leading to limp-mode warnings and rising back-pressure at just 60–70 mph cruise.

VW Golf 1.6 TDI

Low exhaust temps round town and sticky EGR valves leave the DPF sitting above 40 g soot, lighting the dash lamp every few weeks.

Nissan Qashqai 1.5 dCi

Swirl-flap and sensor faults cancel regens, so soot builds until the car drops into reduced-power mode on hills.

Mercedes Sprinter 3.0 CDI

Taxi and shuttle vans spend hours idling; exhaust never reaches regen temperature, so ash loads climb fast.

Peugeot 308 1.6 BlueHDi

Additive tank running dry plus city mileage means the filter blocks early; our chemical flush and forced burn restore flow.

Why It Matters

Clean DPF, Healthier Engine

A soot-packed DPF blocks exhaust flow. Back-pressure climbs, heat rises, and the turbo, sensors, and injectors all suffer. Our in-garage clean and controlled regen clear the filter, drop the pressure, and let the engine breathe again. You leave with quicker throttle, better MPG, and cleaner emissions—all from one visit.

FAQ’s

Have Questions About DPF Cleaning?

Straightforward Answers From Mobile Regen Experts

What is DPF cleaning and how is it different from a forced regen?

DPF cleaning combines a chemical flush with a controlled, dealer-grade forced regeneration. The flush dissolves soot and ash that a normal regen can’t burn, then the regen safely raises exhaust temperature to finish the job. A forced regen alone may clear light soot but won’t remove baked-on ash.

How do I know my DPF needs cleaning rather than replacement?

If back-pressure readings are high (usually above 25 kPa) and the soot load sits over 70 g, but the substrate isn’t cracked, a professional clean restores flow at a fraction of the cost of a new filter. We take live pressure readings before recommending a replacement.

Does mobile DPF cleaning really work?

Yes. After the three-stage flush and regen, we show you live data: soot mass drops, pressure falls, and exhaust temps return to normal. Most vehicles leave with the DPF light off and throttle response restored.

How long does a full clean and regen take?

Setup, chemical soak, and controlled regen typically take 60–90 minutes on your driveway or depot bay. No towing, no overnight workshop stay.

Is DPF cleaning safe for my engine and sensors?

Absolutely. We use manufacturer-approved chemicals and monitor exhaust temperature, pressure, and O₂ levels throughout the process. No parts are removed, cut, or welded.

How much does professional DPF cleaning cost?

Mobile cleans range from £150 to £250 depending on engine size and soot load. That’s far less than the £1,000+ cost of a replacement OEM filter.

How often should a DPF be cleaned?

With mainly motorway driving, a DPF can last 100,000 miles between cleans. City-based vans may need attention every 25,000–40,000 miles. We advise based on your driving pattern and pressure readings.

Will a clean help me pass the MOT emissions test?

Yes. A clear filter reduces particulate output and prevents the “DPF tampered or full” fault that causes instant MOT failure. Many customers clean the DPF a week before their MOT for peace of mind.
