It may be the control module within the steering wheel - sometimes referred to as a comms unit. This unit amongst other things controls the lights, wipers and communicates with the BSI.

Sometimes a BSI reset below can help:

• Put the driver's window down, lift the bonnet and ensure all equipment is switched off.
• Ensure all doors are closed and remove key from the ignition.
• Wait for 3 minutes, disconnect the vehicle battery and wait at least 3 minutes.
• Reconnect the vehicle battery, wait a further 3 minutes (do not open doors).
• Switch on the side lights through the driver's window.
• Switch on the ignition (don't start car) and check system's functionality.
• Hold lock button on key down for 10 seconds.
• Remove key open & close door test central locking system.
• Start the engine and complete the system's check.
• Failure to follow this procedure could result in incorrect operation of many BSI related items.

Otherwise getting it connectetd to a Lexia / Diagbox will provide a better diagnostic before replacing parts. I wouldn't go anywhere near the BSI at this stage as that is a very sensitice ECU that controls most of the car's other ECUs.
