If it is I plan to play at virginizing my bsi as my car is knackered, if I get it to work I'll post step by step how I did it, using which tool and which software

I assume by trawling the tinterweb for a month now I have to:

1. desolder the one on my bsi and read/save the file
2. Get a virgin dump from same BSI number/Year/Trim, I also think, but am not 100% sure that the info from the original dump file can be used as a base to virginize if I can't get a virgin dump online, think you ffff some of the data
3. Copy the good info to the blank (new) Eeprom, however, I think my Eeprom info is scrambled, this is currently the fly in the ointment as copying the information would surely just copy the knackered information to the new chip, or I just flash virgin to new Eeprom and write Vin, keycode, stereo, reversing sensors, leccy windows etc to virgin bsi using PP2000 as new BSI - (Keycode was from Trustme from VIN, top bloke, quick and cheap)

** I am assuming that you can't use PP2000/Galletto 1260 ECU Diagnostic Cable and BDM100 flashing programme/cable to virginize my current bsi in situ, i.e. delete all information and start again without desoldering the chip, because if you can I'd be pissed off as I could have done this weeks ago instead of waiting (and buying) Eeprom reader/flasher, Galletto 1260 ECU Diagnostic Cable and BDM100 flashing programme/cable

I'm doing this because my car hasn't started in a month, cranks but not starting after flat battery and jump start, if I get it sorted by doing this and it helps someone else then your welcome to the information with the caveat that if you break it it's your fault

I may be naive and this process is being done arse ways but this is why I joined this forum and posted the information so wiser folk can say - "NO, don't do that" or "yeh, your on right track" or even "you can plug pp2000 in and wipe the chip from OBD2"

Hi Gaz,

The EEPROM chip will be different depending on which model of BSI you have. At some point, Peugeot changed the BSI systems, around 2007/8. At this point, the electronics in the cars became very reliable as a poke around the forums just shows issues with >2006 cars.

Best way forward would be to simply buy a similar BSI to your original, desolder the EEPROM, copy the data into a dump file, then virginise it, installing it back on.

Has the best tutorial. I wouldn't recommend his hack of not de soldering the chip though.
