Best PSA cable interface, for newer cars year 2016 - 2024?

[elfer]

Hi i am struggling with PSA Group i have diagbox, their software, activated, but vxdiag, cant read all ecu and all data properly specially on cars year 2020 or even cars year 2017 and up.... with bosch mts 6531 i see other ecu and other errors which i dont see with vxdiag but still i dont have the full picture... what tool i need to get/buy interface cable. in order to achieve maximum coverage, of course genuine tool is the best but extremely expensive, is there alternative like very very high end clone or something really good, i want to be able to read all. all ecu all modules all live data etcs.. not to scan car with 2 cables and loose time and still not to have the full picture... this is their currently tool i think or you can correct me if i am wrong , PSA CoreXS VCI ?
is there good clone of this or not.

You didn't mention what version of Diagbox you have. That is important as it is constantly updated for later vehicles and system / component modifications and changes.

The interface used is what is termed as a Lexia 3 VCI. These are clone interfaces and a proper full-chip version will be in the region of £100+. Cheaper versions don't have all the hardware components on the boards and this can prevent communication with later multiplexed vehicles.

So your issue may be two problems - software version and / or interface.
