Engine control unit for excavators and construction machines
Excavator, loader, grader, compactor or dump truck stopped by its engine control unit? We supply a genuine unit, matched to your engine serial number and shipped ready to fit.
On a job site, one machine down often stops a whole crew. Construction machine units live in harsh conditions: vibration, water, pressure washing, welding done without disconnecting the batteries. When the unit fails, the engine will not run.
Heavy-duty diesel only — no passenger cars.
Signs of a failed engine control unit
- The engine no longer starts although the starter turns.
- Engine or communication fault message on the cab display.
- The engine derates or stops while working.
- The workshop's diagnostic tool no longer sees the unit.
- Unit damaged after welding on the machine, a short circuit or water ingress.
These symptoms can also come from the wiring harness, the power supply or a sensor. Have the wiring checked before replacing the unit: we remind you of this in the quote.
What to send us
- The engine make and model, and its serial number (engine plate).
- The part number on the old unit's label, if readable.
- The machine: make, model, year, and whether it is down right now.
- The delivery country. Photos help but are optional.

Frequently asked questions
Is the engine unit the same as the hydraulic controller?
No. On an excavator, the engine control unit and the machine (hydraulic) controller are two separate units. We supply the engine control unit: its part number is on its label.
Is any adjustment needed after fitting?
In most cases, no. On some machines, additional setup with the workshop's diagnostic tool may be needed: we tell you in the quote.
Do you supply rental fleets too?
Yes: rental companies, civil engineering contractors, quarries and workshops. The invoice is French.
