Question: I need confirmation that Kess v2 v5.017 clone with K-suite 2.47 can unlock PCR2.1 without opening or removing the ECU from car, directly via OBD? And then read and write soft directly to the ECU?
Review 1: you need to open ecu. and unlock PCR2.1 in boot mode.
Kess 5017 I just check 225 version it still say bootmode but also say use tricore tool to read eeprom and write eeprom, select TOOL options, I have not done one of these.
Review 2:
Tested on polo 2011 tdi with PCR 2.1 unlock by obd
As we now see, there are two different opinions.
Thanks.
