hi all came across this bit of info on a site that may be helpful to some of you Peugeot and Citroen BSI (Body Control) units are very prone to failure. Symptoms include no indicators, ignitions lights on with no key, wildly incorrect cluster readings and complete non start. if you are getting any of these symptoms try this rest procedure Failure to follow this procedure could result in incorrect operation of many BSI related items. 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 15 seconds. Reconnect the vehicle battery, wait a further 10 seconds (do not open doors.). Switch on the side lights through the driver's window. Switch on the ignition 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.
