Blocked DPF? We’ll Fix It Fast, Safely, and for a Fraction of the Cost of Replacement
At Remap & Revive, we specialise in advanced DPF (Diesel Particulate Filter) cleaning services designed to resolve common issues like blocked filters, warning lights, limp mode, and failed regenerations. Our proven process restores your DPF’s function without the high cost of replacement, helping your vehicle run more efficiently and pass emissions checks with ease.
Every DPF clean begins with a full diagnostic assessment to determine the severity of the blockage and identify any underlying causes. Using both electronic tools and pressure sensors, we check the soot and ash levels inside the filter and examine the engine data to ensure there are no other faults preventing a successful clean. This diagnostic stage is essential to ensure the cleaning process is effective and long-lasting.
If the DPF is confirmed as blocked and no underlying faults are detected, we carry out our two-stage liquid chemical clean. This industry-leading method involves injecting specialist cleaning agents directly into the DPF to break down and dissolve carbon, soot, and oil deposits. The chemicals are allowed to soak and fully penetrate the filter chambers, loosening even stubborn build-up.
Once the cleaning solution has done its job, we flush the system thoroughly and perform a DPF regeneration to dry out the filter and burn off any remaining residue. Finally, we reset the DPF values in your vehicle’s Engine Control Unit (ECU), so it registers the filter as clean and ready for use — just like a new DPF.
Frequently Asked Questions About DPF Cleaning
What is a DPF?
A DPF (Diesel Particulate Filter) is a component in diesel vehicles that traps and stores harmful soot and particles from exhaust gases to reduce emissions.
Why does my DPF keep getting blocked?
DPFs often get blocked due to short journeys, stop-start driving, poor fuel quality, or failed regenerations. These conditions prevent the DPF from reaching high enough temperatures to burn off soot naturally.
What are the symptoms of a blocked DPF?
Common signs include warning lights on the dashboard, reduced engine power, poor fuel economy, limp mode activation, and excessive exhaust smoke.
4an a blocked DPF cause engine damage?
Yes — if left untreated, a severely blocked DPF can lead to increased backpressure, turbocharger strain, injector issues, and in some cases, serious engine damage.
How does your DPF cleaning service work?
We use a professional two-stage liquid chemical clean combined with diagnostics and forced regeneration. This safely dissolves and removes soot, ash, oil, and carbon deposits, restoring full DPF function.
Is DPF cleaning better than DPF replacement?
Yes — cleaning is far more cost-effective than replacing a DPF, often saving hundreds or even thousands of pounds. Our cleaning process can restore your original DPF to near-new condition.
How long does DPF cleaning take?
Our full DPF cleaning process usually takes 1 to 2 hours, depending on the level of blockage and the condition of the filter.
Do you offer mobile DPF cleaning?
Yes — Remap and Revive offers fully mobile DPF cleaning at your home or workplace for maximum convenience. No need to visit a garage.
Will my DPF warning light go off after cleaning?
Yes — once cleaning is complete and the ECU values are reset, the warning lights will clear, and your vehicle will return to normal operation.
How can I prevent my DPF from blocking again?
Regular motorway or long-distance driving helps keep your DPF clean. Using high-quality fuel, proper servicing, and avoiding short journeys can also reduce future blockages.
Our service is fully mobile, meaning we can come to your home or workplace at a time that suits you. Whether you’re a private vehicle owner, a business running a fleet, or a tradesperson who needs your van back on the road quickly, we offer flexible appointments and competitive pricing, including multi-vehicle discounts.
