As some customers don’t know how to change CAS3 VIN, DME/EGS ISN, etc data using Mini ACDP, this post will share the guide to help you.

In general, there is no need to change CAS data for regular key programming. It applies to change second-hand engine and gearbox or install to other cars after clearing the ECU /gearbox from original car.

CAS3 types supported by Mini ACDP:

How to renew data for CAS3 by ACDP?
1.Run Mini ACDP APP
2.Select “BMW”-> “CAS1~4”-> “CAS3/CAS3+”-> “ICP Mode”

3.Pick the corresponding EEPROM type to read CAS data

Read the EEPROM of the new CAS module, and copy the read EEPROM file to the following directory of the APP: “:/ATmatch/bmw/CAS3/CAS_Renew”, and then select the EEPROM file for parameter calculation.
