I rewired A4 adapter the same as the one on the official website. On my unit there are NM74HC125M, do they need replacing?
I will try tomorrow with my friend's TL866A to read this EEPROM. On CarProg it says verify error.
Can anybody provide a dump from Corsa D 2011 IPC part number: 13312042 or 13312045 ?
I have successfully read & write 93C86, 24C02 and 24C32WP EEPROMs with A4 adapter, rewired like the one on official CarProg website. M35080 is still a no-go, probably it is dead. My IPC doesn't work. IPC is version 3.11, year 2011. Has anybody some dump with this version and year? Thank you very much!

after much forum trawling...
i managed to read my 080D0WQ using an old eprom programmer, under M95080 device
by pin converting it, mainly confirmed by pinout pics from this thread ...
080D0WQ ---- programmer socket
pin 1 ---- pin 4
pin 2 ---- pin 1
pin 3 ---- pin 3
pin 4 ---- pin 2
pin 5 ---- No connection
pin 6 ---- pin 6
pin 7 ---- pin 5
pin 8 ---- pin 8
managed to get a dump .. have attached it ..
trying to find the security code from it, and change mileage to 48k (althou i doubt i will be able to program it!)
which address are they at ? or what program do you use to extract code, and milage ?? .
cheers for any help ... Mick ..
Here is with new mileage, pin code is 7950

Thank you levisdj, that was quick to... will give that a go..
with the pin conversion, can even read it with cheap ch341a usb reader ive found now too !!..
what program did you use ?or did you do it manually ??...
Cheers Mick

Manually mate... not sure you can erease 080 with that stuff... but you can always get a new one!
no not able to currently erase that first 32 bytes, (as protected) so have ordered a new chip to try ...
althou i think i may of found a way and still using the cheap USB CH341a,
using flashrom program, along with some dedicated commands to set the bit off, going to have a play anyhows!
but i have new chip on order as backup !
Also is it possible to manually change the PIN to 9440 ?? so i dont have to change it with opcom once dash is back in car, so it will start..
have given it ago, and attached, does it look good, should this work ? or are there checksums to correct to ?
just an update, to maybe help others ??
no you cannot edit the pin to suit, or the vin, as yes it must have checksums !!
i received blank 080D0WQ and was blank, with sreg as it should be,
but wasn't able to actually write to that first section with my programmer..
(even managed to unprotect and clear the original chip, all bar that 1st 32bytes)
so using new chip, so that the millage set to zero and rest of check sums ok...
thought i would now use opcom to write changes, as that would sort out checksums...
could redo PIN via opcom, and VIN via OPcom all ok,
but still wasnt able to set mileage via opcom said something along the lines of "parameter not met"
so i just swopped eeprom chip from original broken dash in the end !!
But thankyou for you help anyhows peeps
Hi. I hope someone can help me. I have a 2008 Corsa D 1.4i sport with the Z14XEP engine. I have removed the dump.zipcluster (IPS) and took of the EEPROM (M35080). I read the data and dumped it to a binary file. My calculation shows that the security key is 4124, but I would like someone to verify this ( I don't have carpro so I do it by hand).
Thank you very much.
Thank you. Greatly appreciated
