EGR Delete
Disable the EGR system to improve MPG and reduce engine wear.
EGR Delete (Exhaust Gas Recirculation Removal)
The EGR system recirculates exhaust gases back into the engine to reduce NOx emissions. Over time, the EGR valve and intake manifold clog with carbon, causing:
- Reduced performance
- Rough idling
- Black smoke
- Engine warning lights
Our Service
We turn off the EGR system within the ECU, stopping it from operating and preventing related errors. Combined with physical blanking (if needed), this service increases power, improves MPG, and reduces engine wear.

Frequently Asked Questions
Removing the EGR prevents carbon buildup in the intake, resulting in cleaner combustion, better throttle response, and improved reliability.
No, our software solution disables the EGR function in the ECU, preventing any warning lights from appearing.
The software-side EGR delete typically takes 1-2 hours. If you also want the EGR valve physically blanked off, we can advise on the best approach for your vehicle during the appointment.
Yes. By stopping exhaust gases from being recirculated into the intake, the engine breathes cleaner air and combustion efficiency improves. Many owners report noticeable improvements in MPG after an EGR delete.
Diesel vehicles that do a lot of short journeys or city driving benefit the most, as these conditions cause the EGR valve and intake manifold to clog with carbon deposits more quickly. Popular models include BMW, VW, Audi, Mercedes, Ford, and Vauxhall diesels.
Yes. EGR delete is commonly combined with a Stage 1 remap, DPF delete, or AdBlue delete for a comprehensive tuning package. We can carry out multiple services in a single visit.
Yes. We always save a full backup of the original ECU software before any work. The factory EGR function can be restored at any time if needed.
