ECU 55198930 CN – description
We offer a Magneti Marelli MJD 603.S3 ECU intended for the Opel Corsa D with the 1.3 CDTI engine. The housing is refurbished; the electronics have never been repaired. The Car Pass (PIN) code is reset (Virgin), so the ECU is waiting to be programmed in the car.
How to check compatibility
The most reliable way is to compare labels. Your ECU should show the number 55198930 CN (55198930CN). This unit is intended for the Opel Corsa D with the 1.3 CDTI engine, but the number decides the match, not the model or year.
Typical failure symptoms
- starting problems,
- injector control faults,
- uneven running and misfires.
Water is usually to blame – the ECU sits under the scuttle and blocked drains flood it. Run a diagnosis and clear the scuttle drains.
Programming and fitting

- Paid extras: EGR OFF, tuning and – on versions with a DPF – DPF OFF.
