Mobile DPF Deep-Clean & Regeneration

Fast at-home service fully restores your DPF while you wait, without expensive replacement.

Your Diesel Particulate Filter (DPF) reduces harmful pollution. But it gets clogged up – and sooner or later it stops the engine. If you see a warning light, call us. We come and clean it while you wait, so you can get back to driving as normal. We can be with you next-day, sometimes even same-day.

Why do I have a problem or warning light?

A DPF warning light means the exhaust is blocked by soot. Before long, the car will go into “limp” mode, then stop altogether. Our professional equipment and techniques remove the accumulated soot and ash, and fully restore the DPF so it’s as good as new. You’ll probably also see better economy and engine running.

What will it cost?

We’ll need some basic details about your problem to make sure cleaning is the right solution for you, and to give you an accurate price. Get in touch now – it only takes a minute and we won’t waste your time. Our service always includes inspection, pre and post-clean testing, high-pressure deep-cleaning with chemical solution, 30-day warranty and detailed diagnostic reports for you to keep.

Diesel Particulate Filters: FAQs

See our full list of Frequently Asked Questions on our FAQs page

What is a DPF?

Diesel engines are efficient, but they create sooty particulates in their exhaust that are bad for health. Your Diesel Particulate Filter (DPF) removes the particulates by pushing exhaust gases through a maze of metal channels, collecting the sooty particulates.Engine management systems are supposed to regenerate the filter unit when needed by applying high temperatures to the collected soot. For various reasons this regeneration routine can fail (one of the main reasons is when the car is only used for short journeys, never getting fully up to temperature). When the filter becomes clogged, exhaust flow is blocked. Eventually your engine management will apply a partial shut-down. The filter is a closed unit, and expensive to replace. It can be cleaned, however, with the right tools and techniques.

Can I still drive?

If you have an engine management light on, the problem needs to be fixed – even if the light goes off from time to time. The light means the engine is not working properly. Sometimes, engine management systems will put your car into “limp-home” mode after the fault is detected. That usually doesn’t change till the fault is cleared. You may be able to get home, but until the problem is fixed your car is not really useable. Most garages will prefer to simply replace the DPF unit, but this is expensive and rarely necessary. Fortunately the unit can now be effectively cleaned without removal, at much lower cost.u003cbru003eu003cbru003e(Please note: disreputable garages may offer to cut the DPF out of your system altogether. It is illegal for you to drive the vehicle once this has happened and if caught you can be liable for a fine upwards of £2000. Your car won’t pass its next MOT and will have little resale value.)

What will it cost?

You have the choice of buying a new DPF unit (the most expensive option), or having your current unit cleaned.u003cbru003eDeep-Cleaning and regeneration is the cheapest and quickest option – we’ll give you an exact price, and there are no garage costs for removal and fitting.u003cbru003eWe carry out the deep-clean and regeneration while you wait, so you don’t have to be without your car. u003cbru003eFor an exact price for your vehicle, we’ll need a few details which you can give us on the phone, and we’ll tell you straight away.

This will tell them how full the filter is in terms of percentage and the weight of soot in grams so we understand what we need to remove. Alongside this we are also checking all of the vehicle’s sensor, glow plugs and every other component involved with the DPF system to be certain the faults are not being caused by something else and that the clean will be successful u003cbru003eu003e Full Deep Clean of the DPF – Using our in-house manufactured cleaning solution our engineer will being the cleaning process which will take 45-60 mins to complete u003cbru003eu003e Post-clean Health Check and Investigation: We perform a post-clean health check on the vehicle, again to review the live data to ensure we have removed the contents of the DPF, reset any warning lights and that there are no other fault codes you need to be aware of.

We offer this service for Cars, LCVs, HGVs and construction and plant vehicles such as forklifts and tractors.

Pre-Clean Diagnostics

Before we begin, we perform diagnostics to ensure the vehicle is in suitable condition for a clean and, more importantly, to confirm that the issue is DPF-related and not another underlying problem causing the DPF light to illuminate.

Live Data Check

We then conduct a live data check to assess the vehicle’s readings. This helps us determine if the DPF is functioning correctly and if it is blocked, as well as the severity of any blockage.

DPF Cleaning

Our engineer injects our solution into the DPF. Access points vary by vehicle, and our engineer will use their expertise to select the most appropriate one on-site. The solution expands within the DPF for approximately 40 minutes. Following this, we engage the engine to expel soot and ash from the exhaust (this is the visible part of the process for customers). We then re-check the live data to evaluate the DPF readings; a second clean may be necessary for severely blocked vehicles.

Regeneration

After the clean, we proceed with the regeneration phase, which can be either static or dynamic, depending on whether the customer is present. If the customer is present, we perform a test drive with them, monitoring live data throughout the drive and regeneration. If the customer is not present, we conduct a static regeneration and check the live data upon completion.

Post-clean diagnostics

Once regeneration is complete, we run a second diagnostic scan to review the vehicle’s current readings and identify any remaining faults.

Advice given

Finally, we provide the customer with advice on any necessary next steps if faults are still present. If no faults remain, we offer guidance on how to maintain a clean DPF in the future.
