Piwis tester 2 (power-on password is porsche2018) including ALLSCANNER VCX-PLUG users, attention please: If you got VCI selfcheck error or hard disk data lost? Please do take my tips as follows:

Tip 1, actually Piwis tester 2 selfcheck function is not working, do not click [Settings] – [VCI Configuration], otherwise you will get error.

Tip 2, Piwis hard disk is not compatible with other computer, but only CF30 packed with Piwis tester 2.Do not take outthe hard disk from the CF30 laptop and install it on other computers, otherwise the data maybe get lost and hard to recover.
