The first Porsche Integrated Workshop Information System tester is commonly called PIWIS I. Porsche RJ describes its introduction in 2004 and its relationship to KTS 650 hardware. Its original operating instructions describe a touchscreen unit booting Windows XP before starting the Porsche application.
The 2006 manual’s page 10 shows the PIWIS start screen, with diagnostic, wiring-diagram, fault-finding and information entry points. Porsche software and its licence are separate from Bosch ESI[tronic]; a similar enclosure does not establish that an unmodified Bosch tester is a genuine PIWIS unit.
Photographs show Porsche-labelled light-coloured equipment and Bosch-green devices configured with Porsche software. Verify the individual unit and provenance rather than treating colour as conclusive.
