Got a DPF fault? Is your DPF clogged? Want to avoid expensive replacement fees for your DPF?

Our diagnosis and 2-step cleaning is your best option!

Why does it get clogged up? There are numerous reasons why a DPF may become saturated ranging from incorrect driving habits to failed components such as sensors and EGR valves that must work correctly for the DPF to regenerate (clean itself out). The biggest mistake we see with DPF issues is incorrect or lack of diagnosis and assumption that simply cleaning the filter will resolve the problem. Until a DPF issue is diagnosed there is no point cleaning the filter. We have a great wealth of knowledge and specialise in the diagnostics of DPF systems. Our diagnostics includes live data analysis and manual filter pressure testing. 

If required how do we clean the filter? We use a 2-step chemical system that is pressurised in through the DPF pressure sensor pipe directly into the DPF. This means in the majority of instances there is no requirement to remove the DPF for cleaning.

    Amazing service very friendly guy enjoyed talking to him n asking questions on how it works i have learnt somthing new today and the results are amazing i have and can notice a different in my car before i had it done my engine was loud and was running rought at idle and sluggish at pull off it seemed to take a while to get to speed, now after having a 3 stage clean it is now alot quieter and its a hell of alot more smoother at idle and it pulls off nice and quick its an all round smoother drive im well happy with the results i will recommend this to people 🙂 5 stars all the way

    Had my 2007 ford focus St carbon cleaned today... Made a huge difference on the over run and really noticed that extra pull especially in first gear. Very surprised at the gains considering it is a petrol that already runs nicely I would highly recommend this treatment to anyone and if you have a diesel with a few miles on the clock do not hesitate to book it in now for a clean! 🙂 🙂 happy customer 🙂 🙂

    Yesterday Matt came to me yesterday and gave my car a stage 3 clean after months of problems from my Diesel engine not getting a proper run.
    It was smoking, coughing and spluttering and wouldn't start at times due to a valve sticking in the EGR unit.
    Accelerating through the gears you would notice a large vibration in gears 1,2 & 3!
    After the cleaning was done I couldn't believe the difference, no smoke, no problems with a sticky valve and a tiny little vibration in 1st gear, the engine is smoother, increased power from the turbo and an all round better response in driving.
    I WOULD RECOMMEND CARBON CLEANING TO ANYBODY WHO ACTUALLY CARES ABOUT THE VEHICLE THEY DRIVE!!
    I dealt with Matt who was very knowledgeable and was happy to listen to me about the history of the vehicle since owning it and I learnt a few things to.
    I will be booking in again down the line!

    If you know what your looking at then you can tell the difference between the pics.

DPF Cleaning with Tiff

Understanding the DPF System

Emissions requirements for new vehicles require Particulate Filters to be fitted to the exhaust of diesel vehicles since the ‘Euro 5’ standards were enforced in 2009. Prior to this many vehicles also have a DPF fitted in anticipation of the change to regulations. This ‘Euro 5’ and beyond standards aim to deliver reductions of >80% in soot (diesel particulates). However, these filtration systems are not without problems causing DPF warning lights, engine limp mode safety activation, reduced efficiency/mpg and poor engine performance.

The diesel particulate filter is mounted as part of the exhaust system. In order for the filter to operate correctly, it must regularly run a regeneration process to burn off the continuously accumulating soot. This process is completed by precisely regulating an increased temperature of the exhaust gas passing through the filter which then burns away the carbon deposits. To do so a sensor transmits data to an engine control unit that then calculates the precise requirement for post-injection fuel to increase the temperature during the regeneration phase. As with any filter, the DPF must be regularly emptied otherwise, over a period of time, it will start to clog up and will eventually become partially blocked. Passive regeneration of the DPF can only occur at fast speeds on a motorway or A-road so with all the local driving and short journeys for many vehicles this process cannot occur often enough eventually leading to clogging of the DPF.

How does the DPF Regeneration process work?

Passive regeneration

The DPF system is designed in such a way that when the engine is consistently running at approximately 2,500 rpms or more (e.g. on a motorway or fast A-road) the exhaust gas temperatures exceed 350°C soot particles are constantly being burned off without any engine management intervention.

Active regeneration:

Where the vehicle is predominantly used for urban mileage the exhaust gas temperatures fail to get hot enough passive regeneration is no longer achieved. Therefore soot particles are no longer being burned off so start to accumulate inside the filter. This leads to clogging of the filter and when a threshold is reached the engine’s control unit (ECU) triggers the active regeneration at its next opportunity. The amount of soot accumulated inside the DPF is calculated by the ECU based on:- ‘Driver profile’ – whereby the ECU records the pattern of exhaust gas and oxygen temperature sensor readings and then calculate the degree of saturation, and DPF flow resistance’ – whereby the ECU records signals from sensor regarding flow, temperature and pressure and then calculates of the degree of saturation.

The pressure is measured at both the inlet and outlet of the DPF and the degree of saturation inside the filter is measured by the pressure sensor calculating the difference between the two readings. As the filter becomes clogged the voltage transmitted by the pressure sensor to the ECU rises. At a manufacture set voltage reading the ECU will proceed to raise the temperature of exhaust gas to approximately 600°C thus actively starting the regeneration process. The ECU instructs this increase in temperature by:

  • Regulating air flow through the Electronic Throttle Control (ETC).
  • Switching the Exhaust Gas Regeneration (EGR) valve so that it recycling exhaust gases thus increasing engine combustion temperature.
  • Enforcing a post-injection following the principal injection in order to increase the combustion temperature.
  • Enforcing a second post-injection which leads to unburnt fuel evaporating inside the combustion chamber. The unburnt hydrocarbons are oxidised by vapor inside the catalyst converter. During these stage temperatures inside the DPF can reach 620°C.
  • The sensor signal, upstream of the DPF, supplies the ECU data to determine the quantity of fuel to be injected during the second post-injection.

Forced regeneration:

When the DPF system has exceeded a set level of saturation it becomes impossible for the vehicle to perform a passive or active regeneration. A mechanic may at this stage attempt what is known as a forced regeneration using a computer to instruct the DPF system to heat up (similar to the active regeneration process) and burn off the excess soot. Depending on the vehicle this will either be done whilst driving or possibly stationary with the engine running and the ecu controlling the RPMS.

Unfortunately all too often forced regenerations will fail or only be beneficial for a short period of time. Why? Simply because either the saturation is too high or the operator has not diagnosed and repaired the fault causing the DPF system to fail the process.

If a forced regeneration fails its common practice you’ll be told a mechanic that a new DPF is required and at huge expense. In most instances this advice, even when it’s from the manufacturer dealers, is inaccurate!

What it more than likely means is the mechanic has reached the limit of their understanding of a very complicated system and therefore assumes the DPF has completely failed. In our experience, this diagnosis is rarely correct. For most replacing the DPF will only resolve the problem short-term, with the fault still present it’s only a matter of time before the new expensive DPF  also becomes saturated.

As a preventative measure against clogging of DPF’s we recommend an engine carbon cleaning treatment every 10,000 – 12,000 miles.

If your vehicle has a DPF issue, or has even failed a DPF regeneration by a professional, and therefore requires professional intervention to diagnose and resolve the problem there is no better alternative than a skilled UKCC technician.
