Frequently Asked Question
1. Why should I clean my DPF instead of replacing it?
Replacing a DPF can cost £1,000–£3,500+. Professional cleaning restores up to 98% of original performance at a fraction of the price (from £150). Cleaning is safe, effective, and proven – saving you money while keeping your vehicle compliant.
2. What are the benefits of a clean DPF?
- ✅ Restores engine power and performance
- ✅ Reduces fuel consumption and running costs
- ✅ Prevents limp mode and breakdowns
- ✅ Ensures MOT emissions compliance
- ✅ Extends the life of the filter and other engine components
3. Is it legal to remove my DPF?
No. Removing or tampering with a DPF is illegal in the UK and will cause your vehicle to automatically fail MOT testing. Fines for DPF removal can reach £1,000 for cars and £2,500 for vans.
4. What’s the difference between DPF cleaning and forced regeneration?
- Forced regeneration: burns soot at high temperature inside the car, but cannot remove ash or oil deposits.
- Professional off-car cleaning: removes soot, ash, and oil using water-based MET technology, fully restoring airflow.
5. Are aftermarket or cheap replacement filters a good option?
Most cheap aftermarket DPFs fail quickly, cause repeated faults, and may not meet emissions standards. A professional clean of your original filter is almost always more reliable and cost-effective.
6. How often should I clean my DPF?
It depends on driving style, mileage, and vehicle type. On average, every 70,000–100,000 miles or sooner if symptoms appear (warning lights, limp mode, high backpressure).
7. Can DPF cleaning improve my MPG?
Yes. A blocked DPF increases backpressure, making the engine work harder and burn more fuel. A clean DPF improves efficiency and often restores lost MPG.
8. How long does the DPF cleaning process take?
Standard turnaround is 24–48 hours. For local customers within 10 miles of Yeovil, we also offer a same-day service on request.
9. What vehicles do you service?
We clean filters from:
- Cars (petrol & diesel with DPF/FAP)
- Vans & light commercial vehicles
- 4x4s & pickups
- Fleet and trade customers (garages, delivery companies, taxis)
10. What are the warning signs of a blocked DPF?
- DPF or engine warning light
- Loss of power / limp mode
- Poor fuel economy
- Strong exhaust smell or smoke
- Increased regeneration frequency
11. Can a blocked DPF damage my engine?
Yes. Driving with a blocked DPF causes high exhaust backpressure, which can damage the turbocharger, injectors, and engine seals.
12. How do you clean the DPF at DPF MaxCare?
- Initial flow test and inspection
- Soak and reverse flush with water-based solution
- Thermal drying
- Final flow test with results in mbar
- A written/digital report with before-and-after readings
13. Will my car pass MOT after cleaning the DPF?
Yes. A professionally cleaned DPF restores proper emissions flow, helping your vehicle meet MOT standards (provided no other engine faults exist).
14. Do you provide proof of cleaning results?
Yes. Every filter comes with a before-and-after flow test report in millibars (mbar). This is your technical proof that the filter has been professionally restored.
15. What if my DPF cannot be restored?
Some filters are beyond repair (e.g. melted substrate, internal collapse, heavy oil contamination, metal debris). In these cases, you will still receive a report confirming the issue. The service fee remains payable, as the full cleaning and testing process has been carried out.
16. Do you guarantee your cleaning service?
Yes – we guarantee that your DPF will be cleaned and tested professionally with measurable results. However, we cannot guarantee recovery of filters with pre-existing internal damage.

36. How to prevent DPF blockage?
Regular vehicle servicing, timely cleaning, and using quality fuel can help prevent DPF blockages. Occasional long drives at motorway speeds also allow the filter to regenerate naturally.
37. Can DPF cleaning solve the warning light issue?

Yes, we provide professional DPF cleaning and regeneration for cars, vans, trucks, and commercial vehicles. No matter the size of the vehicle, our service restores filter performance effectively.
