My ecu has immo defeat.
I flashed several files, all files were correct check summed.
I flash one file before 4-5 days and car worked fine for at least 10 times (ignitions/start ups).
Yesterday i couldnt start up the car. ABS and ESP flashes which indicates immo problem.
A eeprom read reveal several miss written blocks inside. Flash my working eeprom file and car runs fine.
My question is what could have cause such weird behavior?

032RP but hadnt problems before and i ve flash it dozens of times.
Unfortunately dont have other flash cable, i am waiting uni usb programmer these days to arrive.
Whats your suggestion? Also friend of mine faces same problem after 400km of driving, for first time and he uses other tools for flashing (original expensive one).

Check your instrument cluster for a 20 pin soic ic labled magamos res very common problem on vw seat skoda and audi immobilisers corrupts data transfer causing none start situations.

I think your eeprom is damaged or you have a Problem with the connection from the eeprom.

My problem was solved after flashing my previous working file with the changes from the newer file.
The newer file (flash file on 29f800b) i flashed somehow provokes this weird behavior, cause both file were 100% same (ultracompare shows 100% match and winols no difference). Sometimes winols traces differences on check sum areas but bits had same values..(perhaps clarity issues?)
I am digging it as deep as i can go, but for now my time is very limited so ll take time to (if) find exactly what triggers it.
