55566400 HQ – Magneti Marelli MJD 602.M1 ECU in Virgin version
Magneti Marelli MJD 602.M1 module for the Opel Meriva with the 1.3 CDTI engine with the Car Pass (PIN) code reset. The housing is refurbished; the electronics have never been repaired. It just needs fitting and programming in the car.
Why 1.3 CDTI ECUs fail
The ECU is mounted under the scuttle, so when the drains get blocked, water floods it. A fault shows up as starting and injector control problems, uneven running and misfires. Run a diagnosis before buying, and clear the scuttle drains before fitting.
