WHY YOU NEED OUR DPF DELETE SOLUTION WHICH ALSO SAVES YOU MONEY
(DIESEL PARTICULATE FILTER) DPF REMOVAL
DPF (Diesel Particulate Filter) removal is remedy for the current wide-spread emissions system failure on later model diesel vehicles. This very common failure occurs when the DPF gets old or fails to regenerate as per the normal factory regen process. Once the DPF becomes blocked, the car will usually go into Limp Home Mode until the problem is fixed. This has been known to leave people stranded in the bush, in remote country towns or when 4 wheel driving. A forced regeneration of the DPF will usually only last for a short period and will require a new $3000.00 DPF from the manufacturer.
A DPF Removal Service we are offering worldwide means that we can correct this problem from ever happening again. We can also combine a DPF (Diesel Particulate Filter) removal (known as DPF OFF) together with EGR OFF (Exhaust Gas Recirculation removal) and a Performance remap of your factory ECU. In short, we can help correct problems with DPF and poor performance at the same time. For more information please call us on 02 80901881 .
The process involves reading the current factory engine management file / program (your vehicle’s Factory ECU) and with this file we then customise it for whatever the customer desires or whatever fixes need to be applied: Whether it be a Performance Tune, turning off the DPF and EGR or the Speed Limiter etc (ie DPF OFF, EGR OFF and SPEED LIMITER OFF). Then, we flash the new customised file into the factory ECU and test drive the vehicle to confirm the tune is OK. Then we are done. You then have the opportunity to experience the amazing results from the first time you test drive the vehicle.
WHAT IS A DPF?
A DPF is a device designed and integrated into the Diesel Engine exhaust system to trap and remove Diesel Particulate Matter from the exhaust gasses of the diesel engine. Much like the Catalytic Converter on conventional petrol engines, the DPF works to remove harmful toxins and lower the emissions of your diesel engine making it more environmentally friendly.
The aim of the DPF is to remove 80% of the diesel particulate matter (emissions) and although a great concept, it brings about a whole new line of problems. We are taking calls constantly from anxious customers and mechanics across the country when their DPF light is illuminated on the dash, indicating that there is at least a partial blockage in the DPF system.
DPF PROBLEMS YOU MAY NOT KNOW ABOUT
Passive regeneration is an automatic regeneration which often occurs on drives where there is prolonged high exhaust temperatures like for example on motorway type runs, but it can’t be said that all cars get the required long journey motorway type trips necessary to complete a passive regeneration of the DPF system and so manufacturers have had to adapt the technology and designing an “active” regeneration process controlled by the Engine Management Computer also known as the Engine Control Module (ECM).
When the diesel particulate (matter) loading in the DPF reaches a pre-set limit (normally around 50%), the ECU will make minor adjustments to the fuel injection timing system which will in turn increase the exhaust temperatures and help initiate the DPF regeneration process. This is a smart way of getting a motorway type temperature to build up inside the DPF system and begin a full regeneration to bring the unit back to good health, however, if the journey is a bit stop/start where you’re in a built up city with traffic then the chances are the regeneration will not complete and eventually the DPF light will illuminate on the dash to tell you that the DPF system is partially blocked. At this point it is recommended that you try to find time to complete a full regeneration and this can be done on a simple 10 minute or so drive of speeds above 80kph.
If you do not do this and choose to ignore the light, it may go out but come back on and as you continue in a relatively slow, stop/start pattern of driving the diesel particulate matter loading will continue to build up and clog up the DPF system until it reaches closer to 75% blocked at which point you can expect other more serious warning lights to appear on the dashboard. By now, driving at speed alone will no longer be sufficient and the car will need to go to a garage or dealership for regeneration. The other lights may be the engine management light constantly on and possibly even the glow plug light blinking constantly. It is not advised to continue driving the vehicle under these conditions to avoid further costly damages to the DPF system and other mechanical components e.g Turbo and Engine.
COMMON VEHICLES SUFFERING DPF SYSTEM FAILURE
The DPF system is fitted to a wide range of cars and in fact is being installed on almost all new Diesel engines so the problem will in future become more and more common, however, at this moment in time we’ve put together a small list of the most common cars which we’re having to deal with on a weekly basis suffering from the DPF problems:
- Alfa Romeo
- Mitsubishi Pajero
- Nissan Navara
We can do DPF removal on all the above vehicles and many more….
DPF ADDITIVES AND HOW THEY WORK
The most common type of DPF systems feature an in-built oxidising catalytic converter, which is located close to the engine where you will find the exhaust gases will still be relatively hot so that passive regeneration is possible. In some vehicles there’s not always space nearer the engine in which case some manufacturers use a different type of DPF system, one which relies on a fuel additive to lower the ignition temperatures of the diesel particulate matter particles so that the DPF can be located further away from the engine.
The DPF additive is usually stored in a separate tank and is automatically mixed in with the fuel when you go to fill up. Only very small amounts of theDPF additive are required for regeneration for example on average 1 litre of DPF additive would cover around 2800 litres of fuel, enough to cover circa 45,000 kms at 7.1 litres per 100. With this type of DPF, regeneration would be initiated by the ECU roughly every 300 or so miles depending on the vehicle and will normally take 5-10 minutes to complete. Normally you won’t even notice this process taking place and if anything, once regeneration is completed you might see a glimpse of white smoke exit the exhaust and that’s it.
HOW MUCH ARE YOU EXPECTED TO PAY ON AVERAGE FOR REPAIRS?
Ignoring the warning lights and allowing the diesel particulate (matter) loading to continue to build up will lead to complete failure of the DPF in which case it would require a replacement unit which can cost anything from $4,000 – $10,000 as mentioned above. After replacing the DPF you will need to reset the ECU which is an additional charge, normally between $150 – $250.
Most of our customers prefer to have the DPF removed entirely. We can reprogram the vehicles Engine Control Module (ECM) also known as the Engine Control Unit (ECU) so that you no longer have warning lights being lit up on your dash and at the same time save on fuel costs and gain extra power out of the engine as the DPF system restricts the natural flow of exhaust gasses. Reprogramming the ECU will also eliminate the possibility of the engine running into LIMP Mode caused by the DPF system. We charge $1999.00 for the full drive in drive-out service which includes engine oil and filter service.
WILL THIS CAUSE MY VEHICLE TO FAIL AN EMISSIONS TEST?
Not with us! Though it is illegal to remove any emission device if the system leaves the car incapacitated then removal is the only option. Thus, it is not illegal to remove the DPF if the system is causing the vehicle to leave you stranded and unsafe as is the case when the DPF fails. This can be confirmed by any government motor vehicle facility. What we do is also unique, when we re-map the ECU we download the ECU data and manually search through the 1000’s of data strings to locate and remove all DPF data strings. This is the ONLY sure way to delete a DPF system completely without problems occurring.
Legislation. What the “Environment Protection (vehicle emissions) Regulations” say is….
A person must not, without just cause, alter, replace or modify the engine or the exhaust system or fuel system of any motor vehicle in a way that – (a) departs from the manufacturer’s design: or (b) increases the rate of discharge of any of the constituent parts of emissions or (where applicable) defeats the intended upward discharge or dispersion of the emissions.
Your argument is that you have “just cause“. The vehicle is not fit for its intended purpose with the DPF installed. Having to go for an otherwise completely unnecessary drive every couple of hundred kms to regenerate the filter, or worse having to take the car to a dealer to have a forced regen is totally unreasonable AND CREATES THE VERY EMISSIONS PEOPLE ARE TRYING TO AVOID. Worse still is going into limp mode in a remote location or driving with the caravan or boat up a big hill with a truck barrelling up the road could very well put you and your family in a life threatening situation.
Also, truth be known, there is no road-side testing in Australia for diesel particulate at time of writing. The regulations say nothing about a car with a diesel engine needing a catalytic converter or a DPF. Simply, a VISUAL diesel smoke test is performed by a licensed mechanic.
