DPF Problems? Have you an Engine Management light on your dashboard ?
Has the car lost power and gone into limp mode?
What is DPF Removal & Remapping?
A DPF is a filter in line with the exhaust system that prevents small soot particles being released into the atmosphere.
Like all filter it needs emptying periodically and generally speaking this happens automatically by burning up the particles in a process known as regeneration.
Diesel Particulate Filters are fitted to most diesel cars and, because they need high temperatures to regenerate.
Low mileage stop-start motoring can cause them to become blocked. If this happens and is ignored expensive engine damage can occur.

Our ECU modifications for DPF removal, power or economy are the best in the business.
We offer a Diesel Particulate Filter solution to all our customers, when DPF cleaning no longer works. This package includes an ECU remap, and we also remove the DPF filter from your vehicle. This restores your lost power and improves economy.
Will it affect my NCT or DOE test.
Our software modifications will not affect your NCT or DOE test.
Prices start from €230 (remap only).
What is a Diesel Particulate Filter
What is Remapping
Remapping is essentially reprogramming a car’s engine control unit or (ECU). Your cars’ ECU is made up of a serious of maps – tables of numbers that are changed to improve certain aspects of the how your engine runs.
What is Fuel Additive?
A fuel additive is used to maintain the chemical compound of the soot produced by a diesel engine. Automatically adding a liquid each time fuel is put into the tank. This enables the burning of soot out of the DPF at a lower temperature under regeneration. This system can also be removed from the ECU software therefore ensuring no more engine management lights!
Will my car feel any different?
Your vehicle may already be in a limp home mode, or have reduced engine performance. This power will be restored and all warnings to do with your DPF will disappear. If you decide to have your DPF removed as a precaution, you will notice an increase in power and fuel economy.
This is because the engine will breathe better and the exhaust gases will dissipate much quicker.
What is regeneration?
When you drive for a long time at high speeds, the exhaust reaches very high temperatures. Driving at a high speed for a while will heat the exhaust enough to burn off the soot particles which have been trapped by the DPF. But most drivers to not drive at high speeds often enough or for long enough to rely on this passive regeneration to clear the DPF of soot particles.
Since many drivers do not use their cars to drive long distances on a regular basis. Manufacturers had to come up with a different way to clear the DPF of particles. They came up with a system in which active regeneration is activated when the amount of soot gathered in the DPF reaches a certain level. In most cars, this level is set at 45% of the DPF’s total capacity. When the soot gathered reaches this amount, it triggers the process of post combustion fuel injection which increases the temperature of the exhaust. This way, even if the car is not travelling at high speed, the exhaust becomes hot enough to burn off all of the soot which has collected in the DPF.
Active Regeneration Initiated
If the active regeneration process is initiated, but you reach your destination before it has had time to burn off all of the soot, there is a possibility that the DPF warning light will appear on your dashboard. You should be able to clear this partial blockage simply by driving your car faster than 40 mph for roughly a quarter of an hour or so
Engine Management Light
Be careful if the warning lights come on your dash, as continued use can cause further damage to your engine. Components such as your turbo or catalytic converter may be damaged. Also if a vehicle is trying to regenerate too often, you will find the oil level can in fact rise to a dangerous level. This is due to fuel getting into the oil, and where this happens it can cause serious damage to your engine.
How we remove your diesel particulate filter.
We do a complete diagnostics test on your car to verify any faults and problems you are having with your vehicle.
We reset your ECU clearing all the faults.
We take a copy of all the information from your vehicles ECU.
We remove the DPF filter from your car and cut a small opening and remove the internal filter. We then weld it back together and replace the unblocked filter to your car.
We then program the new data on to your vehicles ECU.
We test drive your car to ensure everything is working as it should.
Finally we will do a last diagnostic test to make sure everything is correct and that there are no pending faults.
We charge €300 for this service at our garage in Offaly.
