BMW MS45 / MS45.1 ECU Cloning Service (Plug & Play)

Restore full plug-and-play functionality to your BMW with our professional MS45 / MS45.1 ECU Cloning Service. This service transfers all original data—including VIN, immobilizer (EWS/CAS), coding, and adaptations—from your old ECM to your replacement unit, ensuring seamless startup without additional programming.

How It Works:

Send in your ECUs: Ship your old ECU (MS45 or MS45.1) and your replacement ECU to us.

If the old ECU is dead: Include your CAS (Car Access System) module and key instead.

We handle the rest: Using professional BDM bench tools, we perform a full binary clone (not partial copy) to replicate all factory data safely.

Fast turnaround: Your cloned ECU is usually shipped back within 1–2 business days after arrival.
