ECU fault-code diagnosis before DTC calibration assessment
A diagnostic trouble code should never be hidden before the underlying fault is understood. We identify the exact P-code, vehicle, ECU software and hardware modification before considering selective DTC calibration for a lawful off-road, motorsport, export or otherwise permitted application.

Selective engine ECU calibration
Petrol and diesel engine fault-code delete and DTC removal
A diagnostic trouble code records the circuit, signal or operating condition that the ECU has identified. We require the exact generic P-code or manufacturer-specific code, a complete diagnostic report and the untouched original ECU file before any targeted software assessment.
Active faults involving sensors, wiring, fuel, ignition, boost, cooling, lubrication, emissions equipment, thermal protection or vehicle safety must be diagnosed and repaired. DTC calibration is considered only for a documented and technically appropriate permitted application.
Diesel engine fault-code removal assessment
Selected boost, airflow, rail-pressure, EGR, DPF, SCR, sensor and actuator-related entries assessed only after the fault context and intended use are confirmed.
Only the requested diagnostic entries
Unrelated diagnostic monitoring and protections should remain active. We do not recommend blanket deletion of every fault-code table.
Mobile DTC service West Midlands
Car, van, motorhome and campervan ECU fault-code service
Mobile diagnostic and supported ECU programming appointments may be available for petrol and diesel cars, vans, motorhomes and campervans. We can scan the vehicle, review live data and identify whether the warning relates to an active fault, a completed repair, a coding issue or a documented modification.

Commercial and worldwide ECU support
HGV, truck, LDV and pickup ECU DTC file service
Commercial-vehicle fault codes may be tied to engine derate, torque limitation, aftertreatment, sensors, actuators, CAN communication or manufacturer-specific monitoring. Each request is checked against the original ECU data rather than processed as a generic file.
Worldwide online DTC removal file service
For equipped workshops in the UK, Ireland, Europe and worldwide. Submit the original read, ECU IDs, exact codes, scan report, read tool and method, modifications and lawful-use declaration.
Postal ECU DTC programming
Tracked postal or courier service for supported ECUs from England, Scotland, Wales, Northern Ireland, Republic of Ireland and Europe. Send label photographs before shipping.
HGV, LDV and pickup fault-code assessment
Selected DAF, MAN, Scania, Volvo, Mercedes-Benz, Renault Trucks, Iveco, Ford, Isuzu, Mitsubishi Fuso and pickup applications assessed by ECU version.
Modified hardware and known diagnostic entries
Sensor-disconnection and engine-flap DTC assessment
Disconnecting a sensor or flap can trigger open-circuit, short-circuit, plausibility, position, flow and performance codes. A fault-code change does not make defective hardware safe and must not be used to disguise a roadworthiness issue.
DTCs after a sensor is disconnected
The exact sensor function must be identified. Crank, cam, fuel-pressure, temperature, knock, brake, airbag and other safety-critical or engine-protection signals are not suitable for indiscriminate suppression.
Swirl flap and intake-manifold runner codes
Actuator, position, linkage, manifold contamination and wiring should be checked first. For a documented permitted modification, related diagnostic entries can be assessed with the correct calibration.
Throttle, exhaust and engine flap codes
Throttle-valve, exhaust flap, intake shut-off and related control strategies vary by ECU. Software must match the actual hardware configuration and the complete remap.
DTCs after ECU remapping
Codes appearing after a remap may indicate incompatible calibration, checksum, torque-monitoring, hardware or pre-existing faults. Diagnose the cause before making further changes.
Accurate information prevents file errors
What we need for an ECU DTC request
Exact vehicle details
Registration, VIN, make, model, year, engine code and transmission.
Complete diagnostic scan
Exact P-codes or manufacturer codes, status, freeze-frame data and symptoms.
Original ECU identification
Hardware/software IDs, ECU label, read tool, method and untouched file.
Modification and repair history
Parts replaced, disconnected hardware, existing remap and intended legal use.
Safety and road-use compliance
An illuminated engine malfunction indicator can be an MOT defect, and suppressing a DTC does not repair the condition that triggered it. We do not disable diagnostic monitoring for unresolved safety-critical, engine-protection or roadworthiness faults. Specialist code-table changes are offered only for lawful off-road, motorsport, export or otherwise permitted applications; the vehicle owner remains responsible for compliance.
When this service may help
Common symptoms and requirements
Persistent engine-management or P-code warning
Persistent engine-management or P-code warnings require diagnosis of the underlying circuit or component. Software assessment is considered only after the fault context and intended lawful application are confirmed.
Known diagnostic entry after a documented modification
For known diagnostic entry after a documented modification, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
ECU file requires selective code-table assessment
For ecu file requires selective code-table assessment, our assessment checks the relevant vehicle data, control-module communication and supporting evidence before the correct next step is confirmed.
Multi-brand capability
Cars, vans and specialist modules
DTC diagnostics and permitted targeted ECU file assessment are available for supported petrol and diesel cars, vans, pickups, LDVs, motorhomes, campervans, HGV trucks and selected commercial or specialist vehicles. Compatibility depends on the exact ECU family, software version, original file and diagnostic-code format.
Compatibility for ECU DTC Removal & Engine Fault-Code Delete Service depends on model year, controller manufacturer, hardware, software and previous programming history. We confirm these details before booking to avoid unnecessary travel or module removal.
Before you book
Frequently asked questions
What is ECU DTC removal?
DTC removal is a targeted calibration change that suppresses a specified diagnostic entry in supported ECU software. It is not the same as clearing fault memory with a scan tool, and it must not be used to hide an active mechanical, electrical, emissions or safety defect.
Can you remove petrol and diesel engine fault codes?
Selected generic P-codes and manufacturer-specific engine codes can be assessed on supported petrol and diesel ECUs. Supply the exact code, complete scan report, original ECU read, vehicle and ECU identifiers, modification details and intended legal use.
Do you provide mobile DTC service around Birmingham?
Mobile diagnostics and ECU assessment may be available around Birmingham, Stourbridge, Dudley, Halesowen, Wolverhampton, Walsall, Solihull, West Bromwich, Kidderminster, Bromsgrove and Coventry. Software availability depends on the ECU and fault context.
Can an ECU be sent by post for DTC programming?
Selected ECUs can be accepted by tracked post or courier after compatibility is confirmed. Send the VIN, engine code, exact codes, ECU label photographs and original diagnostic report before shipping. Online file service is also available for suitably equipped workshops worldwide.
Can DTC removal be combined with Stage 1, DPF or AdBlue calibration?
For a supported lawful off-road, motorsport, export or otherwise permitted application, selective DTC changes can be assessed with the corresponding Stage 1, DPF, EGR or AdBlue calibration. The related strategy must be handled correctly; suppressing a code alone is not a complete solution.
Why does the same engine fault code return after clearing it?
A recurring code usually indicates an unresolved fault, intermittent condition or incomplete repair. Diagnostics should establish the cause rather than simply hiding the warning.
Can you correct a false DTC after a legitimate hardware repair?
In some supported applications a software or configuration issue can be assessed after the physical fault is resolved. Legal emissions and safety diagnostics must remain functional on road vehicles.
