It can signal that the internal pump is failing to maintain pressure.
Peugeot electronic control units are notoriously sensitive to voltage drops. If your vehicle's main 12V battery drops below ~12.2V during a starting request, the BSI may undergo an unexpected reinitialisation or drop data communication packets, resulting in key misidentification errors. 3.
