DPF Cleaning Works
One of the most popular is our DPF clean. DPF cleaning can help to tackle a problem faced by increasing numbers of drivers of modern diesel vehicles, whereby the unit becomes clogged with soot or ash often as a result of another component not functioning as it should.
What Is A DPF?
A diesel particulate filter (DPF) is a device which sits within a vehicle’s exhaust system and is designed to “capture” soot/diesel particles to reduce harmful emissions into our towns and cities.
It became legal for vehicle manufacturers to fit DPFs to all vehicles when “Euro 5” emissions standards came into force in 2009, although some VMs did fit them prior to 2009.
DPFs are intended to self-clean, through a process called “regeneration”. This happens under certain diving conditions and the particles are emitted, leaving only a small ash residue. Sensors in the DPF unit communicate with the vehicle’s central computer (ECU) to determine when to clean/regenerate the DPF.
So Why Do DPF Problems Occur?
For a wide variety of reasons, DPFs do not always regenerate when they should, usually due to driving style or conditions, or for technical reasons, such as a problem elsewhere in the engine.
As the DPF fills up and becomes more blocked, a warning light is shown on the dashboard.
If the problem is not addressed, the vehicle’s performance will deplete, the vehicle may go into “limp mode” and become unusable until the issue is resolved.
How Can We Can Help Unblock A DPF?
A standard diesel TerraClean service will help to remove particles from your DPF as part of a preventative maintenance programme.
But when the device is too blocked to allow air to flow through, a different approach is required.
There is a specific tool for DPF cleaning to remove the accumulated particles, and this service is available from us.
Our Technicans who carry our DPF cleans have regular training specifically related to DPF technology, to ensure they are highly competent in diagnosing problems and identifying the correct resolutions.
Should I Remove My DPF?
No. There are companies who will offer to remove the DPF, but it is illegal to remove it and use the vehicle on a public highway: the fines are high and subsequent replacement is expensive.
New MOT rules
have aimed to tackle DPF removal.
Fitting a new DPF is expensive, while cheaper aftermarket units are sub-standard and will develop blockages earlier than the vehicle manufacturer’s specification, so keeping the one you have healthy and clean is important.
We can offer a Induction Clean to help reach the parts of an engine that other carbon cleaning services simply cannot reach.
What Is An Induction Clean?
Direct injection engines are particularly susceptible to carbon build-up on the backs of the intake valves.
More vehicles than ever have direct injection engines, so there is a greater need to service the intake valves separately.
How Does A Induction Clean Work?
The Pressurised Induction Tool provides an effective induction service on direct or conventional fuel injected engines.
After filling the tool’s cylinder with a specially-created Intake Valve and Deposit Cleaner, it is pressurised.
The equipment’s S-Tool attachment is placed directly inside the intake and a fine spray of cleaner is introduced into the system.
The intake valve deposit cleaner is sprayed onto the valves, ensuring that they are cleaned of the hard carbon deposits that affect combustion.
Alternatively, using a vacuum line attachment, the tool can be connected through a vacuum line, allowing for a faster introduction of the chemical into the air intake.
This is an increasingly popular additional service for many owners of petrol-engined vehicles who want to clean an otherwise inaccessible area of the fuel system.
TerraClean How It Works
What Is A TerraClean Fuel System Clean?
TerraClean revolutionised engine carbon cleaning in the UK, but the process is not fully understood by many people.
The marketplace can be a confusing one: lots of products based on old technology are still available, such as ‘pour-in’ solutions. These are cheap and readily-available but fail to provide cleaning in the important post-combustion parts of the vehicle’s fuel and exhaust system.
What follows is a simplified explanation of what TerraClean does, how it works and what it can achieve for your vehicle.
If you would prefer a more in-depth explanation, you can find one here, on the
Science Behind TerraClean page
Why Do Engines Need To Be Carbon Cleaned?
Petrol engines build up unwanted deposits in key areas over time. This consists of a mix of carbon build-up in some places, and sticky substances called tars, gums and varnishes in other areas.
These substances have a negative effect on your engine’s efficiency, reducing MPG and power, and increasing emissions.
TerraClean can remove most of these deposits, leaving your vehicles running closer to its optimum level once more.
What About Diesel Engines?
The patented TerraClean technology used for diesel engines is slightly different, but the principles are the same.
Your engine will be run on our unique fuel to clean both pre and post-combustion, providing all the same benefits.
The TerraClean system will also clean through both Exhaust Gas Recirculation (EGR) systems and Diesel Particle Filters (DPFs), where fitted, providing there is adequate air flow.
Where there is severely restricted flow there are very specific
EGR cleaning and DPF cleaning services
available within the TerraClean family of solutions to address those problems.
The TerraClean End Result.
The end result of a TerraClean is that the vital parts of your vehicle’s fuel system will be cleaner: the combustion chambers, exhaust, cats and lambda sensors.
Your engine will be more efficient, have better throttle response, run more smoothly and quietly and have improved emissions and mpg.
