ECU Repair & Cloning

Common symptoms for ECU repair and cloning

  • No communication with the ECU on diagnostic scan
  • ECU won't power on or respond at all
  • Visible water damage or corrosion on the unit
  • Donor ECU fitted but needs cloning to match the vehicle
  • Repeated, unexplained faults pointing to the ECU itself
Our process

What we check before programming

STEP 01

Confirm the fault is ECU-side

Wiring, sensors and grounds are checked first, so we only commit to ECU-level work once it's the right call.

STEP 02

Remove and inspect on the bench

The unit is opened and inspected at board level for corrosion, damaged tracks or failed components.

STEP 03

Repair or clone

We inspect the existing ECU, recover the required data if readable, then transfer it to a suitable donor unit when cloning is the right route. Postal ECU cloning is available across Ireland.

STEP 04

Programme, refit and verify

The ECU is programmed, refitted and tested to confirm correct communication and operation before handover.

FAQ

Questions about ECU Repair & Cloning

Can a water-damaged ECU be repaired?
Often, yes — it depends on how much corrosion has affected the board and components. We inspect first and let you know honestly whether repair or replacement is the better option.
Is ECU cloning the same as remapping?
No. Cloning transfers the existing software and identity data to a replacement ECU so the vehicle runs as before. Remapping changes the tuning values within that software.
Will cloning affect my immobiliser?
Cloning is done specifically to keep the immobiliser and vehicle systems working together correctly. Any immobiliser-related issues are part of what we check before and after the job.
