What is EGR Delete?

The EGR (Exhaust Gas Recirculation) valve routes a portion of exhaust gas back into the intake manifold to reduce nitrogen oxide emissions. While it does its emissions job, the EGR system is one of the most common causes of problems on modern diesel engines. The recirculated exhaust gas carries soot and oil vapour, which gradually builds up as a thick carbon deposit inside the intake manifold, inlet ports, and on the valves themselves.

Over time, this carbon build-up restricts airflow, reduces engine efficiency, and can cause the EGR valve itself to stick open or closed. The result is rough running, power loss, increased fuel consumption, and often a check engine light. Replacement EGR valves aren't cheap either, and they'll just clog up again.

An EGR delete removes the EGR function from the ECU software, so the valve is permanently closed and no exhaust gas is recirculated. This stops the carbon build-up at its source and is a popular modification at our Rutherglen workshop, especially when combined with a DPF delete and remap.

Frequently Asked Questions

Common questions about this service at Doyen Auto Services

Why does the EGR valve cause so many problems on diesel cars?

The EGR recirculates dirty exhaust gas back into the intake. Over time, the soot and oil in this gas builds up as thick carbon deposits, clogging the intake manifold and causing the EGR valve to stick. It's a design compromise for emissions that causes real reliability issues.

Is an EGR delete legal for road use in the UK?

Technically, removing emissions equipment can affect your vehicle's compliance with emissions regulations. However, EGR delete on its own doesn't usually affect MOT emissions test results because the MOT tests tailpipe emissions, not whether the EGR is functioning. We recommend checking with your local MOT station.

Can you clean the intake manifold as well as doing the EGR delete?

Yes. If there's already significant carbon build-up in the intake, we'd recommend a carbon clean at the same time. There's no point doing an EGR delete if the intake is already heavily clogged — you'll want that cleaned out to get the full benefit.

How much does an EGR delete cost in Glasgow?

An EGR delete typically costs between £150 and £300 depending on the vehicle. We often do EGR deletes as part of a package with DPF delete and a remap, which offers the best value. Call us for a quote specific to your vehicle.
