Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.

I was really impressed with how smooth the entire process was from start to finish. The 2017 Mercedes GLC300 ECM arrived quickly, and it was already VIN programmed, so installation was basically plug-and-play. The team was very responsive and answered all my questions promptly, which made me feel confident about the purchase. Shipping was free and surprisingly fast, which was a great bonus. After swapping out the module, my car ran perfectly with no issues at all. Definitely recommend this service to anyone needing a reliable ECM replacement.
