Title: Decrypting VAG EDC17 Immobiliser Data Post by: Team dz on May 21, 2025, 06:39:14 AM Decrypting VAG EDC17 Immobiliser Data
ECM EDC17C46 Part OTP : id cpu : 410009071400284F74080010110C0400 offest : 17F00 DATA EEPROM data crypte :D9385C35C78E30A8E61434B6DB offest :808C to 8099 CS:5C35C78E30A8E6 MAC1:1434 MAC2:D938 PIN:B6DB Data after decryption CS="B8 47 32 FB EF 47 00" MAC="6F 8F 24 C5" Config="00 00 00" PIN="11352" I'm looking for a suitable method or algorithm to decrypt data. I've tried many data inversion and data conversion attempts, but to no avail. What I've understood from most forums is that they talk about half-duration. ID CP 8 BIT It is the decryption key.

I was not able to resolve it either It probably has any kind of byte rotation, multiple xors, decimal convertion.... |
