Incidentally I also have a C4 Picasso with Stop/Start. I have disabled Stop/Start but Economy mode still kicks in, frequently after just 5 minutes. Citroen have gone to great lengths to include this feature but I cannot see how starting the engine after 5 minutes can preserve the battery. I now carry a small transistor radio in the car.
Finally managed to get communication to the ecu after cleaning all earths, disconnecting-reconnecting wiring and got the following faults with delphi p1590, p0104, p0238, p0183, p1471, p0122, p0405, p0193, p0104, p0113, and a 40A Oil level gauge - No symptom fault on the BSI module.
Muchas gracias patricio.. MirarĂ© la BSI aver si tiene algĂşn pin suelto o algĂşn relĂ© Ya que actualizar el software no tengo manera de hacerlo y en la citroen no se atrevieron actualizarla. Y me pedĂan 500 por cambiar la BSI.. Cosa que como están las cosas no puedo hacer. Muchas gracias por tus respuestas.. Aver si me ánimo y cotilleo
Question to C4 owners with Actia interface : Could you do me a favour and print to PDF (or just made a Print Screen) your BSI configuration ( please hide your VIN). I would like to look for differences beetween working configuation an my friends one. P.S. Sorry for possible mistakes, unfortunately my English isn't native
Is the outside temp data used for anything engine management wise, or could it be that when the BSI unexpectedly resets it sends the MPG/Range readouts off a bit as it starts re-learning Any idea what would cause an unexpected BSI reset, its been logged 4 times on the car now

The positive wire has touched the metal ECU case and has blown the ECU.
Each time DP3 will try to restore, also as commanded in the log-file, the original flash. But for some reason DP3 take all time the "BSI_JC_FLASH_M00" and stops at 99%. In the MCC card/storage there is some other 992 kbyte flash with name "BSI_JC_FLASH_01" which is the +/- SAME as the attached flash from tech-cz.
