Important Note

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I recently bought this ECM for my 2012 Mercedes ML-Class, and I couldn’t be happier with how smoothly everything went. The unit arrived quickly and was already programmed to my VIN, which saved me a ton of hassle. Installing it was surprisingly simple — it truly was plug and play with no complicated steps. Since swapping it in, my vehicle runs flawlessly and feels like new again. I appreciated the clear instructions and could tell the seller knows their stuff. Definitely recommend if you need a reliable replacement ECU.
