citroen berlingo 2007 problem milleage

**spantor** · 16th November, 2019, 07:03 PM

I really do not understand this problem. As I committed the epprom bsi was desoldered, the epprom of the dash uses the tweezers, I have programmed epprom bsi again for 290000km, then I have desolded eeprom dash and I have programmed for 290000km. Now the dash shows 420000km. I really don't understand what happens. I'm going to leave it like this, the vehicle had around 502000km so I think I had some luck. I don't want to risk more.
Thank you all and if someone could say because these things happen I will be very grateful.

The original dash file is number 11 of the files that I attach. But this was extracted using the tweezers. However, the bsi file was extracted with the desoldered epprom.
Is it possible to use other dash files?

juste dump the eprom to a file . then run the the car to increase the milage then dump the eprom in a second file then compare those file with some kind of hexeditopr to see what changed . the eprom chip might have some sort of checksum ... data might be encoded in some kind of coding

Sorry, why do you say so? For not having desoldered the dash's eeprom? I did a job previously on a peugeot jumpy and directly used the epprom clamps of the dash, everything went well.
In this case it has not been so. For the next job I will desolde all the epprom and publish the files here, I will ask someone kind to help check the files in case they are corrupt and modify the mileage. I think it will be the best way to act.
Sorry for not following all the tips.
