What Is the Exhaust Gas Recirculation (EGR) System?

The Exhaust Gas Recirculation (EGR) system is an essential emissions control component in modern diesel and petrol engines. Its primary function is to recirculate a portion of exhaust gases back into the engine’s combustion chamber, reducing nitrogen oxide (NOx) emissions. While this process benefits the environment, it can cause long-term issues for your vehicle’s performance.

At FM Auto Remapping, we specialize in EGR delete solutions that optimize your engine’s efficiency while addressing common EGR-related problems.

What Is an EGR Delete?

An EGR delete involves disabling or removing the EGR system from your vehicle. This is achieved by blocking the recirculation pathways and reprogramming the Engine Control Unit (ECU) to ensure the engine runs smoothly without the EGR system.

How Does an EGR Delete Work?

1. Assessment: Our technicians perform a full diagnostic assessment to evaluate your vehicle’s EGR system.
2. Physical Block: The EGR valve is blocked or bypassed to stop exhaust gases from recirculating into the engine.
3. ECU Reprogramming: The ECU is reconfigured to operate optimally without the EGR system.
4. Testing: After the deletion, we test the vehicle to ensure enhanced performance and reliability.

Benefits of an EGR Delete

An EGR delete offers numerous advantages for both diesel and petrol vehicles:

• Improved Engine Performance: Eliminates the reintroduction of exhaust gases, allowing the engine to burn cleaner and more efficiently.
• Reduced Carbon Build-Up: Prevents soot and carbon deposits from accumulating in the intake manifold and valves.
• Better Fuel Efficiency: Optimizes combustion for improved mileage, particularly in diesel engines.
• Lower Maintenance Costs: Eliminates the need for costly EGR valve repairs or replacements.

Is an EGR Delete Legal?

The legality of EGR deletes varies depending on your location and the intended use of the vehicle. In most regions, removing or disabling emissions control systems for on-road vehicles is prohibited. However, EGR deletes are often permitted for off-road or motorsport applications.

At FM Auto Remapping, we ensure compliance with local regulations and provide expert advice to help you make informed decisions. Learn more about emissions compliance on our blog post.
