ECU and diagnostic support in Pontypridd
Replacement ECU solutions
Depending on ECU type, the solution may involve cloning, virgin preparation, pairing, coding or transferring vehicle-specific data.
Advanced fault finding
We can analyse DTCs, live data, CAN communication, sensor values and wiring before deciding whether the ECU requires bench work.
Fast enquiry process
Send the registration, postcode, fault codes and photos on WhatsApp or through the quote form.
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.
