What to do?

[barbaren]

Is there anyway to clear the saved files?

[frog]

Do you really need to fill in the entry in the service zone? It seems that PP2000 only gets here after the faults have been erased. See also viewtopic.php?f=1&t=11944 and viewtopic.php?f=1&t=11951

hmmm ... could also be that the EEPROM in the engine ECU is full and needs to be emptied. See https://www.lesamisdelaprog.com/lecture ... leine.html where it says:

After a lot of research, I think I have found the cause, that would be a memory saturation of the 95P08 which is on the EDC15C2 (3 connectors), this small EEPROM has a limited capacity and the number of services zones (history) is limited to 50.

that I know. But how do I erase/delete them?

Don't shoot me but my understanding (as mentioned once by my diagnostic mechanic) is that Peugeot and Citroen ECU's will only allow 50 'clear error log' attempts. After this I think the ECU kinda locks out, might be worth speaking to a company like BBA Reman?

You will have to "virginize" the EEPROM. I don't have experience in that...

Another option (that I also don't have experience with) may be (see https://www.lesamisdelaprog.com/lecture ... l#post7742):

I found how to do it without modifying the eeprom with Diagbox

You must clear the history of the fault log in the BSI.
The erase function is no longer available in Diagbox itself (only reading is possible, erasing is no longer possible).
It is possible only via PP2000 / LEXIA, that is why it is necessary to take an old vehicle to have PP2000 / LEXIA (In Diagbox).

The deletion of this log will also clear the faults of all computers (without having to enter Km, for new zone APV, as for the injection ECU for example)!

kind of what I was afraid of.

But it is not a difficult job, should be half an hour at most for a car electronics specialist.

I'd be interested to know if virginising this EEPROM just means writing 0s over all of its memory.

This is the case for the BSI EEPROM certainly, but I would like to know if the same applies for the EDC15 one.

No, afaik that will brick the EDC15C2 . I think there are some factory default parametes in there that must have a correct value.

There are loads of forums out there where people upload their EEPROM dump and ask for a virginized version of it. The people who answer use special software that can "virginize" such a dump. For example "Immotool", see here http://www.digital-kaos.co.uk/forums/sh ... ost2457026 . If you can get a recent version of that tool, i'd be interested!
