VAG Bosch MD1CS014 TC299 in FLEX
Back to press center

Version 8.4.0.0

FLEX introduces support to VAG Bosch MD1CS014 TC299 control units, that can now be managed directly inside your workshop through the Boot Glitch mode. No shipping, no RFT service.

Boot Glitch mode allows you to unlock and program independently, reducing working time and leaving you full control over the operations.

This new protocol is available for all users with a Flex Full Master (FLS0.5M) or Flex Full Slave (FLS0.5S) license.
