Citroen Hints & Hacks


Currently there is a different BSA for each model that Citroen produces. Although the boxes are different, in general they use the same connectors and a large number of the connector pin have the same function.

The BSI is a computer much like the PCs we have at home. Like a PC, when working on any vehicle fitted with a BSI there are certain procedures that must be followed to avoid corruption of the software and loss of pre-programmed settings or memories.

Failure to adhere to the correct procedures can result in a non-start, a loss of configuration or a burnt out BSI. All of which are time consuming to rectify.
