JCB Machinery ECU (Bosch DCU17) and Tractor ECUs (Landini, Kubota, Isuzu) – Repair & Cloning
Feedback from garages and vehicle owners
Supported ECU data transfer, with compatibility checked first.
Engine ECUs for construction and agricultural machines: JCB machinery with Bosch DCU17 control units, Landini tractors (Bosch MD1), Kubota (Denso) and Isuzu industrial engines (Bosch MD1). A dead ECU can stop a machine in the middle of the season. We repair your own unit or clone it to a replacement, and can come to the machine by arrangement.
Common faults
- Machine will not start or the ECU does not communicate
- Engine derates, cuts out or goes into limp mode
- Water, dust or vibration damage inside the case
- Damage after welding, jump starting or a wiring fault
A fault code alone does not prove the ECU has failed: supply, earths and wiring often cause the same symptoms. Send the codes and a photo of the label on WhatsApp before ordering.

Questions
Repair, cloning or replacement – which do I need?
If your unit has a repairable fault, repair keeps your original and needs no programming. If it is damaged but readable, cloning to a matching used unit is usually cheapest. If it cannot be read or repaired, we quote a replacement with your data transferred where possible.
Will the car need coding after the work?
Not after a repair or a successful clone – the immobiliser and coding come from your original data. Some units need adaptations reset after fitting.
Does a fault code prove the unit is faulty?
No. Supply, earths, wiring, sensors and actuators can set the same codes. That is why every unit is tested first and you get a written report.
What if my unit is not faulty?
You pay only the bench test and receive the report to show your garage.
Do you remove immobilisers or emissions equipment?
No.
Not sure of the part number?
Send a photo of the label on WhatsApp or by email before ordering and we confirm the right service.
