EGR fault help when the engine runs rough
EGR faults can cause smoke, rough idle, poor throttle response, limp mode and repeated engine management lights. Before advising on repair or software options, we scan the vehicle and check whether the EGR fault is genuine or being triggered by another airflow, boost or sensor problem.
Send your registration and symptoms and we will confirm likely options, price, and mobile availability before you book.
Common EGR symptoms
- Engine management light: EGR flow, position or plausibility faults stored in the ECU.
- Smoke or rough running: Sticking valves and carbon build-up can disturb airflow and combustion.
- Limp mode: The ECU can reduce power when EGR, boost or MAF readings do not match expected values.
- Repeated repairs: Coolers, valves and sensors can become expensive if the root cause is not confirmed first.

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.
