At Kernowsport, we specialise in mobile EGR removal and performance ECU remapping, helping vehicles across Cornwall—from Hayle and Redruth to Truro and Penzance—boost engine response, reduce emissions buildup, and improve reliability.
Why Remove an EGR System?
Constant recirculation of exhaust gases causes carbon buildup, slows turbo response, and lowers fuel efficiency.
Faulty EGR valves lead to warning lights, degraded performance, and increased DPF strain.
Benefits of Our EGR Delete Service
Sharper Throttle Response & More Power
Improved MPG thanks to cleaner intake air
Lower Maintenance Costs, less soot buildup
Cleaner Combustion & Intake Health
Why Kernowsport?
We deliver bespoke EGR removal—not just masking issues with code deletes. Our process ensures your engine operates cleanly and efficiently. Fully mobile, we reach customers across:
Hayle & St Ives
Redruth & Camborne
Truro & Falmouth
Penzance & Lizard
Important Legal Note
EGR delete is approved strictly for off-road, race, or export vehicles. Removing the system from a road vehicle may lead to fines of up to £1,000 for cars or £2,500 for light commercial vehicles under UK regulations.

Improve Engine Performance with Expert EGR Delete Solutions
At Kernowsport, we offer expert EGR removal services for diesel vehicles across Cornwall and the surrounding areas. The Exhaust Gas Recirculation (EGR) system is designed to reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gases back into the engine. While this helps meet environmental standards, it often causes performance issues, reduced fuel economy, and costly repairs over time.
Our EGR delete services are designed to improve reliability, boost engine efficiency, and reduce long-term maintenance costs—perfect for off-road, agricultural, or motorsport vehicles.
What Does the EGR System Do?
The EGR system reduces NOx emissions by redirecting some of the exhaust gases back into the engine’s intake manifold. This process is managed by the EGR valve, which is controlled by the vehicle’s Engine Control Unit (ECU). A pressure sensor monitors the amount of gas flow to help the ECU maintain balance.
However, this constant flow of sooty gases causes carbon buildup, leading to valve blockages, turbo boost issues, and power loss.
Common Problems with EGR Systems
Carbon buildup leads to sticking EGR valves
Reduced turbo efficiency due to a disrupted closed-loop system
Poor fuel economy and sluggish performance
Recurring fault codes and warning lights
Increased wear on DPF systems
When the EGR valve fails or sticks open, your turbocharger can’t generate the necessary boost pressure. This results in noticeable drops in power, increased emissions, and higher fuel usage.
Benefits of EGR Delete
At Kernowsport, we offer safe and professional EGR delete software solutions that are tailored to your vehicle’s ECU.
✅ Boost Performance
Disabling the EGR valve allows your turbocharger to operate in a closed loop, resulting in better throttle response and increased power output.
✅ Improve Fuel Economy
With no exhaust gases re-entering the intake, your engine burns cleaner and more efficiently—leading to improved MPG.
✅ Reduce Maintenance Costs
No more blocked EGR valves or costly system repairs. Avoid expensive issues with your diesel particulate filter (DPF) by removing excess soot at the source.
✅ Cleaner Engine Operation
Eliminating EGR reduces contamination in the intake system, helping to preserve your engine’s long-term health.
Why Choose Kernowsport for EGR Removal?
We provide fully customised EGR removal and ECU remapping services, ensuring the system is properly disabled—not just masked with code deletes. Unlike quick fixes, our process prevents the EGR valve from operating entirely, ensuring no backflow of exhaust gases.
Our team is trained in the latest diagnostic and ECU software tools to ensure a safe and reliable solution.
Is EGR Removal Legal?
EGR removal is not illegal to perform, but it is an offence to drive a vehicle on public roads that no longer meets its original emissions standards. According to Regulation 61a of the Road Vehicles (Construction and Use) Regulations, driving a vehicle with a removed or disabled EGR system could lead to:
❌ £1,000 fine for cars
❌ £2,500 fine for light commercial vehicles
At Kernowsport, we only offer EGR delete services for off-road use, motorsport applications, or vehicles intended for export.
