The Peugeot/Citroën Built-in System Interface is a control module, essential to the vehicles. It controls a large amount of the vehicle’s operation. Given its many tasks this module is very susceptible to failure. Given the cost of a new module and the main dealer prices for an exchange of a failed BSI, the “BSI exchange” special function provides a cost effective way out for the customer, allowing a repair shop to adapt a second hand BSI

This dialog allows you to read the whole content of the one BSI (JCI or Valeo CAN) and transfer it to the new one. It is very important to use the same hardware type of the replacement BSI. The Valeo BSIs are two types - the old one is thick, while the new one is thin, so they can’t be mistaken. The JCI BSIs are also two types, but they can’t be identified by their exterior, because both are thin. In this case take a look at the sticker for a HW version

The BSI from the picture is V5.01 and can be found in vehicles from 2008 to now. The older vehicles have HW version V2.00 and are typical from 2004 to 2008.
