Could it be M35080 v3 Vs v6 Vs VP differences in incremental area protection...

the E46 earlys ones have M35080v3, so you can write without problem.
after that and rest of BMW/Mini have M35080v6 or vp and need to erase first before can write.

So if I desolder the chip I will be able to write it?

need a eraser to erase the first 2 rows before you can write the M35080

Some of the behave like that. That time this happened the chip died while writing. I can still read it and write it but custer does not work.

As for erasing, why cant we just FF the bytes that the eraser erases? What is special about an eraser?

Any why cant we have eraser capability in hextag?

Because mate ... the increment registers start at 00 00 00 when erased so FF FF would max them out 🙂

Google Increment erasing on eeproms .. see what you come up with .

Also check out your menu Items . :)
