What is DPF Cleaning and Why Your Vehicle May Need One

If your vehicle is flashing a DPF warning light, struggling to accelerate, or losing power, then you are not alone. This is a clear indication that your vehicle has a blocked Diesel Particulate Filter (DPF). The DPF plays a crucial role in every modern Euro 6 emission compliant diesel engine. It is a high efficiency ceramic filter designed to trap, store and burn soot and ash particles created during the combustion process. It has honeycomb shaped channels that trap nearly all particulate matter, resulting in your vehicle being compliant and you being environmentally responsible. 

Over time, this unburned residue and trapped carbon begin to build up, which triggers the DPF warning light, slows the acceleration and loss of power. GMM Service & Repairs Limited offers professional Diesel Particulate Filter cleaning service using advanced equipment and onsite techniques such as DPF regeneration and DPF flush. This results in optimal flow rate, improved fuel economy and a drive which feels like a brand new vehicle, and the best thing is that you can achieve all that without visiting a garage as we come to your location on a single phone call.

Signs Your Vehicle Requires DPF Cleaning

A dreaded DPF warning light flashing on your dashboard or an Exhaust Filter Full message is a clear sign that your Diesel Particulate Filter requires attention. This flashing light can trigger a chain of reactions, starting with loss of power, poor fuel economy, or limp mode. If you own a diesel vehicle and make frequent short journeys, then your DPF does not get a chance to complete its natural DPF regeneration and keeps storing particles instead of burning them off. This could trigger the DPF warning light sooner than you anticipate. Our mobile blocked DPF cleaning service restores full airflow, clears warning lights, and gets your diesel engine performing efficiently again, often the very same day.

How Our DPF Cleaning Works?

The best thing about our DPF cleaning service is that we come to you instead of you wasting hours of your precious time in the garage.

Depending on the condition, DPF is subjected to a deep DPF ash clean or a full DPF flush. It is followed by a retest to confirm the results. We provide a detailed report showing the flow rate achieved after cleaning, the filter’s weight and internal condition in the report.

Why We Use the Ultimate DPF Cleaning Solution – DSC – 17 Pro System

At GMM1, basic flush kits or temporary chemical treatments do not serve the purpose for our DPF solutions. Instead, we use the advanced industry grade system called DSC – 17 Pro Commercial DPF Cleaning Machine that is designed to restore diesel particulate filters to near new performance and is trusted by high capacity garages and fleet operators worldwide for delivering real, measurable results.

Why the DSC-17 Pro Makes Our DPF Cleaning More Effective

Traditional methods used for DPF cleaning are only capable of removing the surface soot and either fail to reset the lights or leave the deep rooted soot remain stuck, the DSC – 17 Pro uses a multi directional air, water and cleaning solution process to penetrate deep into the filter core, removing up to 100% of soot and ash buildup.

Our process starts by checking the DPF condition and taking a pressure reading to measure the blockage levels. DPF of your vehicle is securely mounted into the DSC – 17 Pro machine, where specialist cleaning solution, water and controlled air pressure are used to flush out built up soot and ash from deep inside the filter. To clean every hidden corner, the machine rotates and positions the DPF in multiple directions, and once cleaned, the built-in heated dryer removes all moisture, preparing the DPF for safe refitting. Once the process is complete, we take the second reading to confirm the restoration of the airflow and removal of the blockage.

How does it Make A Difference?

Unlike many garages that offer quick chemical flushes, we aim to deliver a complete professional DPF restoration using advanced equipment. Sticking to such a detailed cleaning process ensures better engine performance, fewer warning lights and limp mode issues, improved fuel economy, longer DPF lifespan, and is way cheaper than replacements. At GMM1, we don’t hide problems; we fix them.
