GODIAG Test Platform For BMW CAS4 / CAS4+ Programming

It’s a bench programming and testing platform designed to hold and interface with CAS4 / CAS4+ modules (the immobilizer/control unit used in many BMW models) so these modules can be accessed safely and conveniently while removed from the car.

 Key Uses

• Program new keys (All Keys Lost): Works with supported key programming tools to create and program new keys even when all original keys are lost.

• Add additional keys: Allows adding spare keys by communicating with a CAS4/CAS4+ unit on the bench.

• Synchronize keys and immobilizer: Test and verify that a programmed key properly syncs with the CAS module before reinstalling it in the vehicle.

• Troubleshooting: Helps diagnose communication and key mismatch issues between keys and CAS modules.

• Data read/backup: Supports reading out and backing up immobilizer data during pre‑processing or replacement operations.
