Bosch KTS 650

Bosch Diagnostics / Bosch KTS diagnostic testers

The KTS 650 is a self-contained touchscreen system from the generation Bosch dates to 2002. Porsche’s first PIWIS tester shares the KTS 650 platform, but runs Porsche-specific software and should be identified by its own labels and configuration.

Hickleys lists update cut-offs for some legacy testers; its published dates are distributor information, not a guarantee of present worldwide support. Verify the exact software release and subscription before purchase.
