Specialist support
A correct solution starts with the correct diagnosis.
EGR symptoms can overlap with intake contamination, boost leaks, DPF loading, NOx or lambda sensors, actuators, wiring and engine-management faults. We review diagnostic evidence before recommending cleaning, repair, adaptation or specialist ECU software for a lawful permitted application.
Our Mobile EGR Diagnostics & Online ECU File Service workflow is matched to the exact vehicle, controller and software identification rather than relying on a generic assumption. This protects readable original data, confirms compatibility and records the work completed.

EGR and engine-management specialists
Petrol and diesel EGR diagnostics.
Exhaust-gas recirculation faults can involve the EGR valve, actuator, cooler, bypass, position sensor, intake contamination, pressure or airflow readings, wiring and engine ECU commands. Petrol and diesel systems differ, so the exact engine and fault context must be identified before repair or software.
NOx, lambda, DPF, SCR and EGR systems can interact. We use fault codes, live data, actuator tests and electrical evidence to avoid replacing parts based on a warning light alone.
Worldwide online ECU files
Online EGR ECU file service for UK, Ireland, Europe and worldwide.
Professional workshops and suitably equipped customers can submit an untouched original ECU read for EGR-related file assessment. Service is available across England, Scotland, Wales, Northern Ireland, Republic of Ireland, Europe and worldwide, subject to ECU support and local legal requirements.
Open Online Tuning FilesInclude full vehicle data
VIN, engine code, ECU IDs, read tool, method, faults, modifications and intended legal use.
Compatibility assessment
EGR, NOx, DPF, AdBlue and performance requests are reviewed against the exact software.

Follow the tool procedure, maintain stable voltage, scan the vehicle and verify operation after writing.
Petrol and diesel ECU assessment
EGR and NOx sensor software services.
For supported lawful off-road, motorsport, export or other permitted applications, EGR and NOx-related ECU file requirements can be assessed together. Software must not be used to conceal a wiring, air-leak, sensor, catalyst or mechanical fault on a road vehicle.
Diesel EGR systems
High- and low-pressure EGR valves, coolers, bypass systems, airflow and differential-pressure data assessed where fitted.
Petrol EGR systems
Valve command, position, intake flow, combustion and related sensor information reviewed on supported petrol engines.
NOx sensor assessment
Sensor position, heater, supply, CAN communication, plausibility and SCR or lean-burn system context checked first.
Combined ECU file options
Compatible EGR, NOx, DPF, AdBlue and Stage 1 requirements can be reviewed together for a permitted application.

Specialist software changes are offered only for lawful off-road, motorsport, export or otherwise permitted applications; the owner remains responsible for compliance.
When this service may help
Common symptoms and requirements
EGR flow or position codes
EGR flow or position codes may be caused by carbon deposits, wiring, sensors, actuator faults or related engine problems. We diagnose the system before recommending repair or lawful software assessment.
Rough running and hesitation
For rough running and hesitation, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
Intake contamination symptoms
For intake contamination symptoms, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
Clear, careful and vehicle-specific.
Send vehicle details
Registration, VIN, engine code and clear module photos.
Confirm compatibility
We check hardware, software, location and service method.

Frequently asked questions
Do you provide an online EGR ECU file service worldwide?
Yes. Supported original ECU reads can be submitted from the UK, Ireland, Scotland, Wales, Europe and worldwide. Send the VIN, engine code, ECU hardware and software IDs, read tool and method, fault codes, modifications and intended legal use. Compatibility must be confirmed before writing.
Can you help with LDV, motorhome and campervan EGR faults?
Yes, subject to the exact vehicle and ECU. We assess supported vans and motorhome platforms including Fiat Ducato, Peugeot Boxer, Citroën Relay, Ford Transit, Mercedes-Benz Sprinter, Volkswagen Crafter, Renault Master and Iveco Daily. Mobile, online-file or workshop support is confirmed case by case.
Do you diagnose petrol and diesel EGR or NOx sensor faults?
Yes. Testing can include fault codes, live data, EGR command and position, airflow, pressure, temperature, wiring, communication and relevant NOx or SCR information. A software file should not be used to hide an unresolved mechanical or electrical defect.
Where is your mobile EGR service available?
Mobile EGR diagnostics may be available around Birmingham, Stourbridge, Dudley, Halesowen, Wolverhampton, Walsall, Solihull, West Bromwich, Kidderminster, Bromsgrove and Coventry. Wider UK attendance is by arrangement and depends on the vehicle, location and technical suitability.
What information do you need?
Please send the registration, VIN, engine code, symptoms and clear photos of relevant module labels.
Is mobile service available?
Mobile attendance depends on the vehicle, location, safe access and technical suitability.
Can you quote from a fault code alone?
A fault code helps us prepare, but it does not always identify the failed component. Diagnostic testing may be required before an accurate repair quotation.
Can I use the online or postal service?
Online file work requires a verified original read and suitable professional tools. Postal work requires clear module-label photographs and approval before shipping. In-vehicle diagnosis cannot be replaced by a file or postal service when physical testing is necessary.
