Specialist support
A correct solution starts with the correct diagnosis.
AdBlue and SCR warnings can be caused by NOx sensors, dosing pumps, heaters, injectors, pressure or level sensors, wiring, CAN communication, crystallisation, software or related engine faults. We diagnose the system before recommending repair, adaptation or a specialist software option for a lawful permitted application.
Our AdBlue & SCR Diagnostics, ECU Software and Mobile 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.

SCR and emissions-system diagnostics
AdBlue fault finding before ECU software.
The SCR system uses AdBlue dosing and NOx feedback to reduce nitrogen-oxide emissions. A warning or remaining-mileage countdown does not identify one failed part, so we assess codes, live data, dosing pressure, temperatures, wiring and related engine conditions first.
Injector and dosing faults
Dosing-command, injector, crystallisation and delivery concerns checked before replacement or software decisions.
NOx sensor diagnostics
Upstream and downstream sensor values, heater operation, power, CAN communication and SCR efficiency monitored where supported.
AdBlue countdown and non-start
Remaining-distance warnings and inhibited-start conditions investigated with the complete SCR and engine fault context.
Combined ECU calibration options
AdBlue, DPF, EGR and performance remapping.
For supported lawful applications, compatible emissions-related file work can be assessed together with a vehicle-specific performance calibration. The original ECU file, full hardware specification and intended use must be supplied.
Explore ECU RemappingAdBlue & DPF software assessment
SCR/AdBlue and diesel particulate-filter calibration reviewed together only for off-road, motorsport, export or another permitted application.
AdBlue & EGR software assessment
Vehicle-specific SCR and exhaust-gas-recirculation file options after the ECU identification, fault context and legal use are confirmed.
AdBlue with Stage 1 remap
A Stage 1 engine calibration for a standard or near-standard vehicle can be combined with a permitted SCR software request where technically suitable.
AdBlue, EGR & Stage 2 remap
Stage 2 calibration requires compatible supporting hardware and a complete modification list. Data logging or workshop testing may be required.
Exhaust sensor testing
NOx and lambda sensor diagnostics.
NOx and oxygen/lambda signals influence emissions monitoring, mixture control and SCR dosing strategies. Software should not be used to conceal a sensor, wiring, exhaust leak or mechanical fault on a road vehicle.
NOx sensor and controller
Live readings, heater status, supply voltage, communication and plausibility assessed before replacement or initialisation.
Lambda / oxygen sensor
Supported pre- and post-catalyst sensor response, heater circuits, mixture values and related fault codes reviewed.
Sensor replacement coding
Selected NOx sensors or controllers may require adaptation, reset, teach-in or initialisation after the physical repair.
Heavy-duty and specialist vehicle support
SCR and AdBlue ECU services for HGVs, LDVs, tractors and motorhomes.
Commercial and specialist diesel vehicles use different SCR layouts, dosing modules, NOx sensors and control strategies. We assess the exact engine, ECU, emissions standard and diagnostic evidence before recommending repair, programming or a permitted ECU software solution.
Supported applications can include rigid and articulated HGV trucks, light commercial vehicles, pickups, agricultural tractors, construction equipment, campervans and coach-built motorhomes. Availability depends on the controller, software version and safe access to the vehicle.

Frequently asked questions
What causes an AdBlue warning or no-start countdown?
Possible causes include NOx sensors, dosing pumps, injectors, heaters, pressure or level sensors, wiring, CAN communication, crystallisation, SCR efficiency and engine-management faults. Diagnostic testing is required because the warning alone does not identify the failed part.
Can AdBlue software be combined with Stage 1 or Stage 2 remapping?
For a supported lawful off-road, motorsport, export or otherwise permitted application, an AdBlue-related file request can be assessed with Stage 1 or Stage 2 calibration. Stage 2 requires compatible supporting hardware and a complete modification specification.
Do you provide online AdBlue ECU files?
Yes, compatible original ECU reads can be submitted for online assessment. Supply the vehicle and ECU identifiers, read tool and method, diagnostic codes, modifications, requested solution and intended legal use. Reading and writing equipment or workshop support is not included unless agreed separately.
Is mobile AdBlue service available in Birmingham and across the UK?
Mobile diagnostics may be available across Birmingham, Stourbridge, Dudley, Wolverhampton, Walsall, Solihull and surrounding West Midlands areas. Wider UK attendance is by arrangement, subject to vehicle, location and technical suitability.
Do you support HGV, tractor and commercial-vehicle AdBlue systems?
Supported HGVs, LDVs, tractors and agricultural machines can be assessed using the exact vehicle, engine, ECU and emissions-system information. Send the registration or serial details, VIN where applicable, engine code, ECU label photographs and diagnostic report so compatibility can be checked.
Can you diagnose motorhome or campervan AdBlue faults?
Yes, many motorhomes use Fiat Ducato, Peugeot Boxer, Citroën Relay, Ford Transit, Mercedes-Benz Sprinter or Iveco Daily base vehicles. Coverage depends on the base vehicle, engine, ECU and SCR generation rather than the coachbuilder alone.
Can I send my ECU by post for AdBlue programming?
Selected ECUs can be accepted by tracked post or courier from the UK, Ireland, Europe and worldwide after compatibility is confirmed. Contact us before shipping with the VIN, engine code, ECU numbers and clear label photographs. Customs, insurance, removal and refitting remain the sender's responsibility unless agreed otherwise.
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.
