This body unit (BSI) from Valeo type x03-00 is the original used part designed for selected PSA cars. It ensures the comfort and bodywork functions of the car and serves as a communication node between the control units. In older dog models, this is a more often changed part, because the failure of BSI is manifested by electrical equipment failures or a start problem.

Especially designed for the Citroën C3 II and Peugeot 207. Before ordering, we recommend comparing parts of parts and marking hardware/software (type x03-00) with your original unit. Code of codes and connectors significantly increases the certainty of compatibility.

What BSI controls: central locking, remote control by key, flashing and lighting, wipers and washer, on -board instruments, communication on the CAN/VAN bus, as well as an immobilizer (key pairing). The failure may be manifested, for example, by spontaneous switching of wiper, non -functional locking, mistakes of communication with BSI, light outages or impossibility to start.

Typical causes of defects: moisture (oxidation), fluctuations or battery voltage, short circuit in the connected peripheral circuit or damage after improper handling. When replacing, always check the condition of the vehicle power and ground to prevent re -damage.

Installation and encoding: The replacement is mechanically simple (access to the fuse box in the cabin), but requires electronic configuration. Follow the disconnected battery – turn off the ignition, wait a few minutes to sleep the system before disconnect the battery. After physical replacement, it is necessary to configure/telecode and pair with the car (VIN, configuration of equipment, PIN keys) using PSA diagnostics (Diabox/Lexia/PP2000), or transfer data from the old unit by cloning. Without the right customization, the central, distance or immobilizer may not work.

Selection Tip: If the hardware series (X03-00) and the main catalog codes match, the probability of proper function is highest. For uncertainty, compare the numbers and visual design of the connectors and verify the compatibility according to the VIN.
