How it works
You will need to send us your donor ISM Module, and we will unlock the used module where it can be programmed to your vehicle using dealer level programmer.
You will have to purchase a new ECU from the dealer or purchase a used working ISM module, and we can unlock it. You can have a certified local Mercedes specialist flash and perform SCN coding to have the vehicle back running properly.
This is an Intelligent Servo Module (ISM) Unlocking Service Only!
