EGR Bypass / Removal / Delete

Stringent emission targets set by the Governmental bodies have forced vehicle manufactures to develop new methods of improving the emissions of a vehicle. One such development is the EGR (Exhaust Gas Recirculation) system. Unfortunately the manufacturers were forced to take a compromise. This was to fit an EGR valve to reduce the emissions of the vehicle, but compromise on the efficiency and reliability of the engine.

By recirculating exhaust gasses back into the combustion chamber during low engine loads the combustion temperatures are reduced and in turn reduce the NOx (Nitrogen Oxide) emissions. Failure often occurs when the dirty exhaust gasses clog up the valve causing it to stick in the open position, when this happens the engine is starved of oxygen and becomes sluggish and inefficient, in some cases the vehicle can become almost undriveable. The EGR valves can also fail electronically when the internal motor or position sensors fail.

The consumer is now becoming wise to the negatives of the EGR system, becoming tired of the expensive repair bills and reliability issues they cause. Therefore, we offer a full EGR bypass / removal service which results in better efficiency and less maintenance costs. Our EGR removal service boast's the following:

• More Power
• Better Fuel Efficiency
• Improved Throttle Response
• Less Flat Spots
• Cleaner Intake System and Engine
• Reduced Maintenance Costs
• Prolonged Engine and Turbo Life

There are two aspect to the EGR Removal service. First the EGR Valve is blanked preventing any exhaust gasses from passing through the valve and entering the intake system (EGR blanking is only required when the valves cannot fully close due to carbon build up or motor failure). Secondly, the ECU is Remapped (Reprogrammed) and the EGR functions are removed from the ECU software or the valve is electronically programmed to remain closed at all times. This is the most important aspect of the service and it is vital that it’s done correctly. We can also remap the vehicle for better performance and fuel efficiency at the same time.

P Code / Fault Code / DTC Delete

Permanently removing fault codes from the engine management system is a very useful process when modifying a vehicle. Removing components such as swirl flaps, EGR valves, other modules etc.. for purpose of performance modification or motorsport will often cause a fault code to be stored in the ECU memory along with lights on the dash and limp mode. By recoding the ECU data and permanently removing the specific fault code we can prevent the dash lights from being displayed and prevent the vehicle from entering limp mode.

AdBlue (SCR) Removal

AdBlue is a chemical liquid used in Selective Catalytic Reduction (SCR) on diesel vehicles in order to reduce NOx levels. The AdBlue fluid (Diesel Exhaust Fluid) is injected into the exhaust system just before the SCR catalyst. The introduction of AdBlue into the exhaust gasses generates a chemical reaction inside the SCR Cat which results in NOx being converted into Nitrogen and Water Vapor. AdBlue was introduced by vehicle manufacturers in order to hit the stringent emission targets set out by governmental bodies.

The AdBlue and SCR system is a relatively complex system with an array of electronic sensors, modules and pumps, these systems can fail and can be expensive to maintain. A vehicle which is used on a regular basis will consume a large amount of AdBlue and the tank will need to be refilled on a regular basis.

Our AdBlue delete service will electronically disable the AdBlue system along with removing the associated dashboard lights and warning messages. Disabling the AdBlue system is normally completed by reprogramming the engine management system. Some vehicles will require a small adjustments also but will be notified by us upon file uploading.

Before committing to a AdBlue delete check your local laws to see if you are legally permitted to have your AdBlue system removed.

Inlet Manifold Swirl Flap Removal / Delete

Swirl flaps are small butterfly valves located within the inlet manifold on modern diesel and petrol engines, they are designed to help regulate the fuel to air ratio, improve emissions and help generate better torque at low engine speeds. At light engine loads the flaps close, causing the air to swirl into the combustion chamber, the swirling affect aids combustion and helps to improve emissions and generate more torque. After 2000 rpm the flaps are generally activated to a fully open position and have very little effect on engine performance and emissions.
