Security code, as in Immobilizer or VATS code, or whatever it's called?

Update- I used a vin change utility and it changed. From there, the SPS flash completed normally.

Using SPS to do a clean re-program of a used E92a. VIN won't change, and the SPS program hangs and fails during the second write. Before attempting to program, got the warning that the VIN in the device is different than the selected vehicle VIN. Three options, accept, override, or cancel. I selecte...

OS 12614676 is the one I'm working on. Found the programming date. Mileage, not yet. Its probably as obvious as the date was when I found it

Kostia, is that from a publicly available document? I haven’t seen it before and would like to read more.

Something as simple as a power cycle and reading/clearing DTCs (even though none were present), seems to have caused the EEPROM area to get written including the p/n identifier from the slave OS and cal, I discovered tonight. This is all on a bench, not in a vehicle.

Tazzi, you’re right. I didn’t mean to say the whole slave os and slave cal gets written. Rather, it looks like the part number identification for both definitely gets written to EEPROM areas. A few places too it looks like. I wonder what command causes that p/n write to happen?

Looking through a couple of E38 binaries at the moment. Could someone point to the last programming date and mileage location. I've found vins all over the place, seed, key, and what I believe to be the Immo code (between the seed and key?). Can't find the date and mileage, though. Nothing obvious i...

I updated the original post, as I've learned more about the various memory addresses. Still not sure how/when the usual slave data gets stored to EEPROM on the E92 (or E38 for that matter).

Thanks to Ironduke, I was able to read full flash for a couple of E92, 2-byte. One is an OEM replacement straight out of the box. I note there is (obviously) no VIN, mileage or programming date in the EEPROM area. I expected that. There is no slave OS, or slave cal data anywhere in the EEPROM sectio...
