Quick answer: Searching for EGR delete Dorset, EGR repair Bournemouth, EGR delete Poole or EGR removal Southampton. If the EGR is stuck, the glow-plug light is flashing, or limp mode keeps returning after every clean, you are in the right place. 24Tuning supplies EGR Repair Software (the professional ECU write people mean when they say EGR delete or EGR removal) for supported cars and vans from £149.

We diagnose first, back up the factory map on supported ECUs, then write the file so the ECU stops monitoring a failed valve or cooler strategy. Mobile across Dorset and Hampshire. Typical visit 1 to 2 hours. 4 year software warranty and 30 day money back guarantee (T&Cs apply) on the file we supply. Call 01202 503 328.

Use the search on this page first. It only lists engines whose ECU record includes the EGR option. If your make does not appear, we do not claim the file for that engine.

What an EGR valve and cooler do

Exhaust gas recirculation (EGR) sends a measured amount of exhaust back into the intake. That inert gas lowers peak combustion temperature so less nitrogen oxide (NOx) forms. On modern diesels an EGR cooler often sits in the loop to bring those gases down before they re-enter the engine.

The drawback is soot. Recirculated exhaust carries carbon that coats the valve, cooler, intake ports and swirl flaps. Short trips around Bournemouth and Poole accelerate that build-up. Valves stick open or closed, coolers crack and leak coolant, and later common-rail setups add flaps, solenoids and sensors that throw their own codes when they fail.

A light clean or a new valve can buy time. When the same EGR fault returns every few months, owners start searching for EGR delete Dorset or EGR removal Bournemouth options instead of another dealer bill.

Common EGR fault codes and symptoms

When we scan for EGR repair Dorset or EGR delete Hampshire work, these symptoms and codes show up constantly. Exact wording varies by tool and manufacturer.

Typical symptoms: loss of power, dull throttle response, limp mode, engine management light, flashing glow-plug light, poor running, white smoke or coolant loss when the cooler has cracked.

  • P0401 / 16785 — EGR insufficient flow
  • P0402 / 16786 — EGR excessive flow
  • P0403 / 16787 — EGR valve / circuit malfunction
  • P1403 / 17811 — EGR system regulation deviation
  • P047F / P0477 / P048A / P048B / P048C — exhaust pressure control valve stuck or sensor faults that often sit next to EGR strategy
  • P1495 — EGR cooler switch-over valve (N345) faults on many VAG and similar platforms
  • Cooler-related: coolant loss, white smoke, poor running with later common-rail cooler flaps and solenoids

Ford Transit, Mercedes Sprinter, VAG TDI, BMW diesels and PSA BlueHDi platforms account for most of our EGR delete Bournemouth and EGR removal Poole visits. Always confirm the stored code on a proper scan — a sticking valve that responds to a clean is a different job from a leaking cooler or a failed position sensor.

Pros of EGR delete software

When people ask about the pros of EGR delete software for Dorset and Hampshire vans, they usually mean ending carbon loops and recurring limp mode without another round of parts. On a supported ECU, a professional write delivers clear operational gains — with honest road-use and DPF interaction limits covered further down this page.

  • Stops recurring EGR fault codes — the ECU no longer expects a failed valve or cooler circuit
  • Clears related management and glow-plug lights — when the write and verification complete on a supported ECU
  • Slows intake carbon build-up — less soot recirculated into the manifold and swirl flaps
  • Can improve throttle response — especially where a stuck-open valve was restricting airflow
  • Reduces oil contamination from soot-laden recirculation — a common complaint on high-mileage short-trip diesels
  • Avoids repeat valve and cooler bills — software from £149 versus recurring dealer parts and downtime
  • Valve can stay in place — software disable leaves hardware looking stock; blanking plates or race pipes are a separate hardware path if needed
  • Mobile across Dorset and Hampshire — driveway or yard visit, typically 1 to 2 hours for the software path
  • Can pair with DPF, AdBlue or Stage 1 — combined quotes when the scan supports it

EGR delete software is not a guaranteed MPG miracle. Some drivers feel freer response once a stuck valve is out of the loop; we do not sell fantasy consumption figures. We also do not fit cheap DIY OBD kits that leave residual codes after a sleep cycle.

What EGR Repair Software is

EGR Repair Software is our name for the ECU write. Search traffic often calls the same job EGR delete Dorset, EGR removal Dorset, EGR delete Hampshire, EGR delete Bournemouth, EGR removal Southampton, EGR delete Poole or EGR removal Poole.

After diagnostics we adjust EGR maps and monitoring so the engine management system no longer drives or expects the failed recirculation circuit. The physical valve and cooler can stay in place. From £149 including diagnostics on a supported vehicle.

Physical blanking plates or delete pipe kits are a separate hardware discussion. Software alone addresses the ECU side. If live data shows a simple clean or connector fault would fix the light, we quote that first rather than selling a write you do not need.

Our EGR delete procedure

Every EGR delete and EGR repair visit across Dorset, Bournemouth, Poole, Southampton and Hampshire follows the same diagnostic-first procedure.

  1. Confirm support — your car or van must appear in the search on this page. Only engines with the EGR ECU option in our database are listed.
  2. Full EGR scan — valve position, cooler switch-over where fitted, flow / deviation codes, live data and related limp-mode logic.
  3. Hardware check — if a cooler leak, wiring short or sticking valve that only needs a clean would waste the write, we quote that path and stop.
  4. Factory backup — read the original software and store a stock file on supported ECUs using Alientech, Autotuner, Dimsport or MagicMotorsport as required.
  5. Custom write and verify — apply EGR Repair Software for your exact software variant, clear the relevant codes, confirm live data before we leave.

Typical software time on site is 1 to 2 hours. Book online with a £50 deposit or call 01202 503 328. If we cannot support the ECU after the scan, we tell you and do not charge for a file we cannot supply.

Honest limits: road use, DPF, MOT and insurance

Road vehicles are expected to keep the emissions specification they were type-approved to. Using a vehicle on the public road after EGR disable that no longer meets that standard can fall foul of construction and use rules. Off-highway, agricultural, site-only and export use cases are different. We talk through intended use before any EGR delete Dorset or Hampshire write. This is not legal advice.

EGR and DPF strategies interact. Disabling EGR while a DPF is still active can change soot loading and regen behaviour. We discuss both systems before writing if a DPF is still in play — and we do not recommend an EGR-only path that risks packing a healthy filter.

Treat the software as a modification and declare it to your insurer. MOT testers look at warning lights and emissions behaviour. An illuminated management light fails the test. We do not promise a pass. If you need a like-for-like valve or cooler repair, say so when you book.

EGR delete Dorset FAQs

Is EGR delete legal in the UK?

Road vehicles are expected to keep the emissions specification they were type-approved to. Using a vehicle on the public road after EGR disable that no longer meets that standard can fall foul of construction and use rules. Off-highway, agricultural and export use cases are different. We talk through intended use before we write anything. This is not legal advice.

Will EGR delete fail my MOT?

The MOT checks warning lights and emissions behaviour rather than reading EGR maps directly. An illuminated management light fails. Treat EGR Repair Software as a modification, declare it to the insurer, and talk intended use through first. We do not promise a pass.

Does EGR delete affect my insurance?

Yes in principle. Anything that changes engine management or emissions strategy should be declared to your insurer. Undeclared modifications can affect a claim.

Does EGR delete affect the DPF?

It can. EGR and DPF strategies interact. Disabling EGR on a vehicle that still relies on DPF regeneration can change soot loading. We discuss both systems before writing if a DPF is still active. See our DPF Repair Software page if that is the main fault.

How much does EGR delete cost in Dorset?

Yes. The file we supply carries a 4 year software warranty and a 30 day money back guarantee (T&Cs apply) when the vehicle stays in the supported configuration.
