Technical Advice Regarding the BSI in Citroën and Peugeot

Model: Citroen Citroen Various
Part: Checks and maintenance

Video tutorial

This video provides technical advice concerning the BSI in Citroën vehicles. First, let's clarify what the BSI is: it is the box that houses the fuses inside the cabin.

This unit communicates with all onboard electronic units, such as ABS, air conditioning, and engine management, enabling various systems to operate according to user requests. The advice given by the YouTuber is that when faults occur intermittently - which is the worst situation as it is difficult to diagnose - the problem often stems from cold solder joints on the BSI terminals.

Therefore, it is important to check the integrity of the cold solder joints on this component, as they can cause significant issues.
