By addressing soot and ash early, you can extend the life of the DPF and avoid future breakdowns.
‘If the DPF lights are coming on, then an early diagnosis is essential to understand why BEFORE the DPF blocks up. If it is already blocked then get it cleaned and flushed ASAP before the blockage causes a split pipe or turbo issues.'

- Differential pressure readings
- Fuel pressure
- Regen status
- Sensor readings

- Loss of power
- High fuel use
- Rough or sluggish driving
- Fans running constantly
- Warning lights for DPF, engine or glow plug
If the filter becomes too full the car may enter limp mode to protect itself.
- Short journeys that never let the car get hot enough
- Stop–start town driving
- Poor-quality fuel
- Faulty sensors
- A rich-running engine producing excess soot
- Low fuel level stopping regen attempts
- Old oil or missed servicing
As soot levels rise the DPF becomes overloaded and the warning light appears.
DPF Cleaning FAQs
Got a question about our DPF Investigation and Clean Service? Here are the answers to the most common queries from drivers across the UK. From warning lights to regeneration issues, this guide explains what to expect before your appointment.
What does a DPF Investigation and Clean actually do?
A DPF clean removes the soot and ash that builds up inside the Diesel Particulate Filter. We start with live data diagnostics to confirm why the filter is struggling. If the DPF is blocked we carry out a deep clean, flush and full recalibration so the vehicle can regenerate properly again. This helps restore performance, reduce smoke and stop repeated warning lights.
How do I know if my DPF is blocked?
Common signs include a DPF light on the dashboard, loss of power, poor fuel economy, repeated regenerations, a sooty smell or warning messages such as Particle Filter Full or Oil Service. If the car feels sluggish or the fan runs constantly, the DPF may be struggling to regenerate.
Can I still drive with a DPF warning light on?
It depends how full the filter is. If the light has only just come on, you may have some time before the car enters limp mode. If the vehicle already feels low on power or another light has appeared, stop driving and get it checked. Continuing to drive with a blocked DPF can cause turbo strain, split pipes and expensive damage.
Does driving the car hard fix a DPF problem?
Not always. “Italian tune-ups” only work when the system is already healthy and able to regenerate. If there is a faulty sensor, low fuel, too much soot or a disabled regen, driving harder will simply add more soot to the DPF. A proper live data diagnostic is the only way to know what the real issue is.
Will a DPF clean fix my warning lights?
If the root cause is soot or ash build-up, then yes. If the warning lights are caused by a faulty sensor, pressure issue, glow plugs or software fault, we will identify this during live data diagnostics and advise you on the next steps.
How long does DPF cleaning take?
The appointment usually takes around one hour per vehicle. This includes diagnostics, cleaning, flushing and recalibration. Some vehicles with severe blockages or multiple related faults may take slightly longer.
Is a DPF clean better than replacing the DPF?
Yes, in most cases. A professional DPF clean is far more cost-effective and restores the natural flow of the filter. Replacement DPFs can cost hundreds or even thousands of pounds. Cleaning often avoids unnecessary replacement and helps keep the original filter healthy.
Do you offer a mobile DPF cleaning service?
Yes. We travel to you across the East and West Midlands, Cambridgeshire, East Anglia and parts of Yorkshire. All diagnostics and cleaning are performed safely on your driveway or workplace.
How often should a DPF be cleaned?
It depends on driving style, mileage and journey type. Vehicles doing short journeys or stop–start town driving may need more frequent maintenance. Many customers book a DPF check and clean every 15 to 20 thousand miles or before an MOT to help avoid emissions failures.
