BMW DME / DDE
BMW DME8
DME and DDE are BMW's names for its engine control units, petrol for the former, diesel for the latter — including when the unit is a Bosch of the MG1/MD1 generation, as on DME8 and DDE8. On those generations, access long meant mailing the unit in; the announcements below track the gradual opening of bench and OBD routes, tool by tool.
What the tools announce
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.
Not a new protocol but an improved OBD Unlock Patch for BMW DME8 ECUs (Bosch MG1CS024, MG1CS049 and MG1CS201, all TriCore TC298). It prevents the FSC-related DTCs (1B2904, 1F2102, sometimes 021204 / 21B210) raised when flashing modified files. Applying it requires a new Bench unlock, even on an ECU already unlocked with an earlier version.
The Bosch DDE8 and DME8 ECUs (BMW) are now supported in Bench read/write on AutoTuner, no mail-in unlock required.
