If any of these sound familiar, a clean usually sorts it. We'll diagnose first to make sure.
A DPF symbol appears on your dashboard — often a filter shape with dots inside. The car is asking for a regeneration cycle. Ignore it and the warning will escalate to limp mode.
Acceleration feels flat and the engine struggles under load. A blocked DPF raises exhaust backpressure, which the ECU compensates for by cutting boost and fuel — your vehicle feels noticeably slower.
A blocked DPF forces frequent attempted regenerations, each injecting extra diesel into the exhaust. You'll typically see MPG drop by 10–20% before any warning light appears.
The cooling fan runs constantly, the exhaust note changes, and the engine idles high after a drive. These signs mean DPF regeneration is happening too often, or failing to complete. A forced regen alone rarely fixes it.
Dark smoke under acceleration suggests unburnt fuel; thick white smoke at idle can indicate diesel pooling in the DPF. Both are signs the filter is no longer flowing properly.
Severely blocked DPFs create enough backpressure to prevent the engine from cranking cleanly. If the car is slow to start or stalls immediately, get it diagnosed before further damage.
Restricted exhaust flow forces the engine to work harder, raising operating temperatures. Sustained high temps will damage the turbo and head gasket if left untreated.
A persistent diesel smell points to a failed regeneration leaving raw fuel in the exhaust system. A burning smell suggests soot is overheating inside the filter — both warrant immediate attention.

"Sy did a DPF clean on our Ford Kuga, very professional and explained everything. Great bloke, would definitely use again."
"Great service today from Adam. Been having issues with the DPF and Adam had this fixed and sorted within no time. Highly recommend, great service and fair prices!"
"After months of trying to get my vehicle fixed and getting palmed off by loads of places, Adam helped me get my car back to normal. Fast service, quality prices, would recommend to anyone."
"Would definitely recommend this company. They spent time on my Mercedes and the Manager came out on his day off to help clean my engine. Couldn't have been any more helpful to a stressful situation."
"Called at 9, the technician was with us by 10.30. Fully explained the process over the phone before arriving."
"Those guys are excellent. We were close to not getting home with our car after a blocked DPF. EngiClean came directly the next morning and even sent a second car out to help. Customer support at its best."
"Came down for a DPF clean on my Porsche and couldn't be happier. Absolutely fantastic from start to finish."
"Very pleased with the work that was carried out, engineer was very professional and explained the process throughout. I would highly recommend EngiClean."
"Great work and service, very professional. The guys even stayed extra time to diagnose and help me with another problem. I am very satisfied, thank you very much!"
A few of the cars, vans and fleet vehicles we've sorted on-site — from family hatchbacks to performance saloons.
For badly blocked filters that won't respond to an on-car clean, we'll remove the DPF, deep-clean it off the vehicle on our mobile rig and refit it — all at your premises.
Stop boxing filters off to specialists and waiting a week. We bring the rig to your unit, clean the DPF off the vehicle while you carry on with other work, and the job stays in-house.
Heavily ash-loaded or severely sooted filters that don't fully respond to an on-car clean can be properly off-car cleaned — often saving the customer over a thousand pounds on a new DPF.
The whole remove, deep-clean and refit happens at your premises in a single visit — not the days you'd wait sending a filter to a cleaning facility.
Run a garage or bodyshop? Everything trade is on the trade DPF cleaning page.
Forklifts, telehandlers, tractors, excavators and generators block their DPFs faster than road vehicles, and they're the hardest machines to get to a garage. So we come to the yard, the site or the farm.
Low speeds, long idles and stop-start loading mean the exhaust rarely gets hot enough for the filter to regenerate on its own. Soot builds, the machine derates, and eventually it won't work at all.
You can't drive a forklift to a garage, and a low-loader plus a week of downtime costs more than the repair. We clean the DPF where the machine stands and it goes back to work the same visit.
The van carries its own generator and full kit, so we're not relying on your supply. A yard, a field or a compound is all we need. No workshop, no bay, no waiting for a slot.
Run a yard, a farm or a plant fleet? Tell us the machine and we’ll tell you straight whether an on-site clean will fix it. Get a price or call 0333 455 9058.
DPF cleaning & engine carbon cleaning — the questions we get most.
A Diesel Particulate Filter (DPF) is part of a vehicle's exhaust system that traps soot from diesel engines, reducing emissions. Over time it fills with soot and needs cleaning to keep the engine running efficiently.
DPFs block when soot builds up faster than regeneration can burn it off. Common causes: frequent short trips, faulty sensors, injectors or EGR valves, poor-quality fuel or oil, and ignoring warning lights.
Loss of power or limp mode, increased fuel consumption, DPF warning light on the dashboard, engine management light, excessive exhaust smoke, and a constantly running cooling fan.
It's not recommended. A blocked DPF increases backpressure, which can cause engine damage, turbo failure, or excessive fuel consumption. Get it checked and cleaned as soon as the DPF light appears.
A proper clean uses approved chemical solutions to dissolve and remove the soot and ash from the filter — that is the service we provide, at your location. Regeneration is not a clean: it is the car burning off soot with exhaust heat. It cannot remove ash, and a heavily blocked filter usually cannot complete one, which is why a forced regen alone rarely fixes it.
Typically every 60,000–100,000 miles, but it depends on driving style, vehicle type, and maintenance. Vehicles driven mostly on short trips often need cleaning more frequently.
Regeneration is the car’s built-in process — it burns soot using engine heat and cannot remove ash. DPF cleaning physically removes both soot and ash using approved chemical processes. Cleaning is what we do; if regeneration keeps failing on your car, that is exactly the sign a clean is needed.
An on-vehicle chemical DPF clean typically takes 1.5–2 hours.
Yes — when carried out properly using DPF-approved cleaning agents, it's completely safe and won't damage the filter, sensors or exhaust system. Avoid DIY household cleaners or untested chemicals.
Yes, if the blockage is the cause. After cleaning, the system is reset. If the light returns, there may be an underlying issue such as a faulty pressure sensor, EGR valve or injector.
EngiClean don't recommend it. Some DIY spray cleaners help with light blockages, but for a fully blocked or ash-filled DPF, professional cleaning is essential. Incorrect DIY methods can damage the filter or void warranties.
Yes. A clean DPF allows better exhaust flow, restoring power, improving fuel efficiency and reducing emissions.
Take your vehicle for a 20–30 minute motorway drive weekly, use low-ash engine oil and quality diesel fuel, keep up with regular servicing, and fix any EGR, turbo, or injector faults promptly.
Yes. After cleaning, we reset DPF adaptation and soot loading values using a diagnostic tool, and verify pressure and temperature sensor readings.
Yes — a 3-month warranty against DPF re-blocking is included with every DPF clean, subject to driving conditions and following our post-diagnostic recommendations.
Engine carbon cleaning removes built-up carbon deposits from inside the engine, intake system, valves, pistons, EGR and exhaust components. It restores engine efficiency, performance and fuel economy.
Over time, unburned fuel, oil vapours and exhaust gases leave carbon deposits on internal engine parts. More common in vehicles used for short trips or city driving, engines with EGR systems, and direct-injection engines.
Rough idling or misfires, loss of power or sluggish acceleration, poor fuel economy, engine knocking or hesitation, excessive exhaust smoke, and increased emissions or MOT failures.
Hydrogen-based cleaning introduces hydrogen gas into the air intake, safely burning off carbon at high temperature. The process is non-invasive and safe when carried out correctly.
Yes — professional engine carbon cleaning is safe for petrol and diesel engines when done with the correct equipment and procedures. It doesn't damage sensors, injectors or turbochargers.
Most vehicles benefit from cleaning once or twice a year. High-mileage or city-driven vehicles may need cleaning more frequently.
Restored engine performance and throttle response, improved fuel efficiency, smoother and quieter running, reduced emissions, and extended lifespan of engine components.
A typical hydrogen clean takes 20–30 minutes, depending on engine size and the level of carbon buildup.
In most cases, yes. Customers report a smoother, quieter engine, better throttle response and improved fuel economy within the first few miles.
Carbon cleaning removes buildup that may contribute to poor performance or fault codes, but it won't fix mechanical or electrical faults. If warning lights are on, run a diagnostic check first.
Yes. By restoring efficient combustion, carbon cleaning can reduce fuel consumption by 5–15%, depending on engine condition.
It's suitable for most petrol, diesel, hybrid and turbocharged engines. Check with your technician if your vehicle has modified or aftermarket parts.
