Reading the catalog identifier
The complete identifier is Toyota_Yaris_1.4_D4D_2007_Turbo-Benzin___66.2KWKW_Bosch_0281012322__391931_D3A9.Original. It names the Yaris, the 2007 model year, a 1.4 D-4D engine, the Bosch controller number and the additional identifiers 391931 and D3A9.
Original labels the file as a stock variant rather than a named modification. It does not by itself identify a particular software change or prove compatibility with every Yaris carrying a similar Bosch part number.
Engine-management context
D-4D denotes Toyota diesel engine technology, while the filename also contains the conflicting label Turbo-Benzin, which refers to turbocharged petrol. The listed output is written as 66.2KWKW. These catalog details should be treated as labels rather than a definitive engine specification.
In practical terms, the ECU uses its calibration to determine how the engine-management system responds to operating conditions. The filename does not establish a specific improvement or special feature for this revision.
