Lancashire & North West.
Suitable initial mobile diagnosis may be available. Workshop testing, programming and repair can then be booked, with collection and delivery offered where appropriate.
In-house electronic testing · Padiham
Local vehicle diagnosis across Lancashire and the North West, plus UK-wide enquiries for suitable removed ECUs and modules. Testing, electronic repair, cloning, programming and coding are completed in-house.


Real workshop evidence
Visible corrosion on both the ECU pins and loom-side connector changes the job. The water path, terminals, wiring, powers and grounds must be checked before repair, cloning or replacement is agreed.
Replace the unit without correcting the cause and the same damage can return.Two service routes
Motorists and garages are welcome. The route depends on whether the fault needs vehicle-side evidence or the ECU or module has already been removed.
Suitable initial mobile diagnosis may be available. Workshop testing, programming and repair can then be booked, with collection and delivery offered where appropriate.
Suitable ECUs and modules can be sent from elsewhere in the UK after we confirm the job. Contact us before posting anything so we can check the unit, scope and evidence, then provide a reference and delivery instructions.
One fault. Several possible routes.
A new ECU can exceed £2,000 on some vehicles. A repair or tested donor may cost a fraction when it is technically suitable—but identification comes before quotation.
Explore ECU cloning & replacement programmingTest vehicle powers, grounds, wiring and communication where the vehicle is available.
Bench-read and inspect the ECU or module, including microscopic PCB work where appropriate.
Repair the original, test a compatible donor, clone supported data or program the replacement route.
Complete the applicable coding, adaptation and final checks without claiming more than the evidence proves.
In-house capability
Testing and data work are matched to the exact module. Not every unit or failure is repairable, and safety-related systems have clear boundaries.
Testing, reading, cloning and coding. View DSG and gearbox TCU services.
Diagnosis, data work and programming according to the unit and vehicle.
Test the reported fault first. VAG SOS complaints are frequently caused by the backup battery rather than the module itself.
ABS testing only—no in-house ABS repair. SRS testing, crash-data reset and suitable cloning/coding; no physical airbag-module repair.
First enquiry
For a first enquiry, send the make, model and year with the registration, VIN or a clear ECU-label photograph—whichever is easiest. If an original and donor unit have already been removed, photographs of both labels are the best place to start.
Identification comes first. The price and correct route depend on the exact vehicle, ECU or module, failure and work required.ECU label, sharp and readable

Both ECU labels when a donor is supplied
Do not delay the enquiry because you cannot provide every photograph. In most cloning cases the units should match exactly, although verified superseded units can sometimes be programmed instead.Removed-unit enquiries
Do not post an ECU or module without speaking to us. A quick identification check can prevent the wrong unit, an unsuitable donor or missing vehicle information arriving at the bench.
Targets depend on access, parts, unit condition, complexity and workload. Warranty is subject to the job-specific terms and covers Engine Clean’s own work—not customer-supplied components.

From the workshop
Different symptoms, different evidence and different outcomes. Each case shows why the ECU, the vehicle and the history have to agree.
