 1L15Y module: it is dismantled from the car.


VVDI Key Tool Plus: it is able to read the BMW CAS4 key information and automatically display the ISN code, so we just need to connect CAS4 module to vvdi key tool plus to program key. If no ISN code, we need engine or key to obtain ISN first.


Godiag GT100 Bench ECU connector: by connecting to VVDI Key Tool Plus, it is able to supply power to it, and it is able to tell if the CAS4 module has a good communication with Key Tool Plus because the indicator will flash.

Here we go, the whole job will be done on Bench.

Step 1. Hardware and cable connection:

Use 16pin cable to connect VVDI Key Tool Plus and Godiag GT100;

Supply power to Godiag GT100;

Connect Godiag BMW CAS4 & CAS4+ Test Platform to GT100;

Connect BMW CAS4 module to the test platform.


Step 2. Turn on GT100 power button and 12V button.



Step 3. Put a CAS4 Key into the hole of the test platform, then press the switch button, the dash indicator will turn blue.



Step 4. On VVDI Key Tool Plus, tap “IMMO Programming” -> Europe ->BMW ->Automatically diagnose models -> Connecting to CAS system -> Generate keys via OBD -> Program key and more.
