Bosch MG1 (petrol)
Bosch MG1CS003
The Bosch MG1CS003 is an ECU of the Bosch MG1 (petrol) family. The tools we resell have announced access by Bench, Boot Glitch and unlock; the announcements, dated and sourced, are below.
MG1 is Bosch's generation of direct-injection petrol ECUs, introduced in 2016 to succeed MED17. It is now found at most European manufacturers. On this generation, access is not always possible through the OBD port: depending on the model year and the make, reading goes through the bench, sometimes after an unlock. The announcements below state, tool by tool, what is open and by which route.

The announcements in detail
Announcements from the tool vendors whose publications we relay, most recent first. Each line links to the original announcement with its date: an opening announced two years ago says nothing about the version you have installed.
Autotuner supports Bosch MD1CP002, MD1CS001 and MG1CS003 ECUs (SPC5777M microcontroller) on BMW Group platforms directly in Bench mode, removing the Mail-in Unlock step.
Flex 8.21.0.0 programs locked BMW Bosch MG1CS003 ECUs directly in Bench mode, without opening the ECU or unlocking it by Boot Glitch. The announcement summary writes SCP5777M where its body writes SPC5777M.
