This index groups selected Bosch M5, MP5 and ML5 designations to make them easier to browse. The prefixes and full suffixes matter: M5.1, MP5.1 and ML5.1 are separate labels, and a shared number does not establish a common ECU, processor or pinout. The ML branch notes that some diagnostic and repair catalogues also use ML labels alongside Volkswagen Digifant.
Processor evidence
A researcher identifies an Intel 87C196KN in the studied BMW M5.2 DME. That is an observation about that ECU, not a confirmed processor specification for every M5, MP5 or ML5 unit. M5.2 research project.
Identify the actual unit
Record the engine code, market, year, Bosch and vehicle-maker part numbers, hardware and software identity, and verify the applicable service information. For the specified Toyota Avensis MP5.4 application, a Bosch diagnostic bulletin warns of high voltage at the diagnostic connector with the engine running; follow the bulletin's equipment and adapter instructions.
