Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.

A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I recently replaced the ECM on my 2012 Mercedes-Benz GL-Class with this unit, and I couldn’t be happier with how smoothly everything went. The fact that it came VIN programmed saved me a lot of hassle, and the install was truly plug-and-play, just as advertised. I was a bit nervous at first since this is a critical part, but the shipping was fast and the fit was perfect. After switching it in, my vehicle started right up with no warning lights or issues. It’s clear that quality and attention to detail went into this product—definitely recommended for anyone needing a reliable ECU replacement.
