ECU and diagnostic support in Swansea
Postal ECU work
This is useful when a local garage has already removed the control unit. Send the label photo and vehicle details before posting so we can confirm the job.
ECU cloning and programming
We support many ECU families and can advise whether cloning, coding, recovery or a replacement unit is the appropriate route.
Diagnostics and tuning
For vehicles that are running, we also provide diagnostic analysis and vehicle-specific remapping where appropriate.
Professional tools for modern control units
Depending on the vehicle, we work with systems from Bosch, Continental, Delphi, Denso, Siemens/VDO and Marelli. The exact ECU number and software version are checked before programming.
Have a fault code?
Send the registration, DTC and location. A photo of the ECU label or diagnostic scan can save time.
Check My VehicleBefore booking ECU work
Do I need to remove the ECU?
No. For mobile diagnostics the vehicle normally stays complete. Removal is useful for some cloning, bench programming and postal jobs.
Can a replacement ECU be made plug and play?
On many systems, yes, but the method depends on ECU family, immobiliser architecture and the condition of the original unit. We confirm compatibility first.
Can you diagnose a vehicle that already had parts replaced?
Yes. In fact, these jobs often benefit from checking live data, wiring, module communication and coding rather than replacing more parts.
