CGDI A2 BMW G Series BDC2 Key Adding by Bench Guide

 In this article, we’ll show how to use the CGDI A2 Key Programmer to add a new key for BMW G series BDC2 on bench.

Step1. Backup Original Data

Connect BDC2 platform with CGDI A2 to back up the original data.

This is a very important step so that if it preprocessing fails, it can be repaired using the back-up data.

IMMO >> BMW >> System selection >> BDC immobilizer(G chassis) >> Coding operation >> Backup Coding

This function backup the current ECU coding data through the OBD connector.

Press Yes to continue.

Backing up coding file, please wait…

The backup is completed, please remove the BDC module from the vehicle and perform the ECU preprocessing function.

Step2. Preprocessing ECU

• Remove the case of BDC2 module. Remember the location of the fuses before removing them.
• After removing all the screws, we’ll need a tool to pry this case apart. Take out the board.
• Then install the preprocessing adapter. Connect the adapter to the BDC board. Connect the power cable and other cable to the CGDI AD host.

After the connection is completed, we can start the pre-processing operation.

Just follow the operation instructions. This process takes about 10 minutes.

BDC immobilizer(G chassis) >> Programming Operation >> ECU Preprocessing >> Yes
