How to read a Bosch number
Diesel engine ECU — EDC15, EDC16, EDC17, MD1.
Petrol engine ECU — ME7, MED9, MED17, MG1.
Transmission, ABS / ESP and airbag units.
Bosch software number — the calibration, not the box. Search it or use the ECU pages.
ECU types and vehicles come from the project properties of our WinOLS library, so they reflect what we've actually worked on rather than a catalogue. Machine-readable: /api/bosch/<number>.
