BMWCAS3+ Module Programming (Cloning) by Post UK
This BMW CAS3+ case study shows postal module programming and cloning support carried out by SG-Tronic Motorsport. The original and replacement CAS modules were prepared on the bench so critical immobiliser and configuration data could be transferred safely before return to the customer.
BMW CAS3+ cloning by post is commonly used when the original module is faulty, water damaged, intermittently failing or when a compatible replacement module needs matching. Bench work can include EEPROM data reading, immobiliser-data transfer, module preparation and verification of communication before installation.
