Launch X431 proS mini is connected to Bluetooth and tested the diagnostic functions and all advanced functions of the Xsara Picasso car, such as resetting the oil or other special functions, and received the same error message: “Disaccording between the software Serial No. and Smartbox Serial No. Please download and upgrade again or contact local dealer”. “disaccording” here should be “mismatch” i thought.
I also tested these cars before:
Volkswagen Passat cc 2009: failed
Volkswagen Passat B6 2007: : failed
Peugeot 308 2011: : failed
Xsara Picasso 2003: : failed
Mitsubishi Outlander 3 2017: : failed
