VVDI2 MED9.1 ECU Adaptation, How to?

Car: It’s a 2013, Scirocco R.

Purpose: I want to adapt a used MED9.1 ECU in another car (Scirocco engine change, want to change the VIN and the CS of the ECU) with Xhorse VVDI2.

I have the IMMO of the old ECU + Cluster and all IMMO Data of the Scirocco where I want to put it into.


First you need to read CS and pin form this used ECU, Hit Automatic detect.

When read that , hit “Read” at top screen.

Then when screen comes On, you put old CS , VIn and pin and hit Write.
