Important: ECM hardware, immobilizer systems, and software configurations may vary by model year. These modules are not necessarily interchangeable across all listed years.

Send your VIN and a clear photo of your original ECM label so ACS can confirm the Mercedes-Benz and Bosch part numbers, hardware compatibility, and programming requirements before shipping.

Programmed (Cloned)

After purchase, ACS emails you a prepaid shipping label to send your original ECM to Hialeah, FL. We transfer the vehicle data, immobilizer information, and coding to a compatible replacement ECM.

Once cloning is successfully completed, the replacement ECM is designed to work with your existing keys without additional dealer programming.

If the original ECM data cannot be read or transferred, we'll contact you to discuss available options.

Virginized

Available for supported part numbers. The ECM ships reset for your qualified shop to program, code, and pair to the vehicle after installation.

Additional diagnostic equipment and Mercedes-Benz programming procedures may be required.

Warranty & Returns

• Lifetime warranty. See ACS warranty terms for details.

• 30-day returns. Contact ACS for return instructions. Ship returns to Hialeah, FL.
