Title: Immo corrupted, weird problem Post by: professor on August 14, 2012, 04:31:15 AM 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? Title: Re: Immo corrupted, weird problem Post by: professor on August 15, 2012, 03:13:35 PM Same problem happened today.
Same conditions, same solution. New bits where written/replaced, new pic attached. Isnt weird or not? Solution if there is more than welcome! Thank you! Title: Re: Immo corrupted, weird problem Post by: s-company on August 16, 2012, 06:08:49 AM which flash tool do you use?

Havent had such problem before, only with the last file i flashed. Title: Re: Immo corrupted, weird problem Post by: s-company on August 16, 2012, 03:13:50 PM which ECU? some ecu are not good to flash with galetto. (for example RS4 with 551K ECU)
did you try another flash tool? Title: Re: Immo corrupted, weird problem Post by: professor on August 16, 2012, 03:30:15 PM 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).

Title: Re: Immo corrupted, weird problem Post by: professor on September 07, 2012, 06:12:13 AM 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. |
