the BSI unit is the built-in systems interface which is at the heart of multi plex wired cars.on a 206 it controls most things from the imobliser to the wipers it is vin encrypted(it will only work on your car) and the worst point is it IS expensive and an absolute nightmare to change.this being because you have to re configure the whole car get one thing wrong and it can take hours to sort!!!!! not good.

Mux is an abbreviation for Multiplexed. The PSA group (which includes Peugeot and Citroen) introduced multiplexing to their cars in 2001, a multiplex car relies on fewer wires to accomplish the same tasks (up to 30% less). It achieves this by sending different signals down the same wire for different components, each component knows what signal to listen for and ignores the others. This saves considerable weight in the car and wiring loom can be smaller. A BSI (Built-in Systems Interface) controls several different networks operating comfort, safety and mechanical equipment through a the single multiplex circuit. The BSI prioritises all the information coming to it so that, for instance, safety matters take precedence when necessary. A further advantage of the multiplex wiring system is improved theft protection. The 206 immobilizer system incorporates mutual interrogation between the BSI and the engine management system.
