Can the Delphi DCM7.1 Renault Nissan 1.5 dCi ECU be cloned?

Yes — this is a service we list for the part numbers below. Your original's data is transferred into a matching donor with the same part number. We confirm your exact label before you post, and you can pay now or when the work is done.

Delphi DCM diesel engine ECUs (and the Delphi CRD units on Mercedes) are fitted by Ford, Peugeot/Citroën, Renault/Nissan, Hyundai/Kia, Mercedes and others. They hold the immobiliser and vehicle data internally, so a second-hand ECU needs your original's data transferred into it before it will start the car.

Which part numbers and versions are covered?

• DCM7.1
• DCM7.1A
• DCM7.1B

Makes: Renault, Nissan
