  • VW_Flash

    Flashing tools for VW AG control units over UDS. Compression, encryption, RSA bypass, and checksums are supported for Simos18.1/6/10, DQ250-MQB, DQ381-MQB, and Haldex4Motion-Gen5-MQB.

  • 3) For highly specialized applications, additional hardware is necessary. For example, on modern ECUs, often read/write access via diagnostic protocol is secured via encryption and signature validation, so to flash custom firmware requires a bypass of these measures. Sometimes this bypass can be via a vulnerability in the diagnostic protocol requiring no additional hardware, like on VW Simos18 , but other times the bypass requires manipulating the control unit beyond what the diagnostic port allows - custom serial protocol, specific sequences of GPIO manipulation, or PWM signals applied to specific pins.
