Hello Team,
I'm quite a noob in this area, sorry for lame questions from the very beginning.
I bought a car (audi a4 b6 1.8 t AMB) and want to play with it by my own. I've never done it before and would be very gratefull for any help possible.
The first thing I wanted to start with is Rear O2 Sensor. Firmware is already downloaded using galletto v54, but without eeprom (need to unlock "case" where ECU is located to use boot mode, without it only firmware is available).
I read wiki, and not everithing is clear now. So I found few XDFs here, and the thing is ESKONF aria location differs on every XDF, so I cannot be sure that ihis is what I need to modify..
Can anyone point me out how to find what I need int the firmware plz
Here is the file attached

Why pattern is AA FF 00? I can find it several times Is data from the wiki inaccurate or not relevant to my block? https://s4wiki.com/wiki/Tuning#Rear_O2_Sensors |

AA FF 00
I got it. The address I need is 00011218. But why there is similar area starting from 0001121F? The only difference in Brake booster pump bit. Сould it be like that one area relevant to automatic transmission and another to manual? I have auto. If I do not have a pattern (like here AA FF 00) how can I find area in this case? For example how to find KRKTE? Sorry for stupid questions again. |

Exactly, 2 versions dont bother with the 3rd. Just change both to the same ( what you wanna code out) and you should be fine. Single value adresses are bit harder to find for newbies, but either you use a similar damos and look where the locations of the maps are , then you go find manually or/and you use IDA to find it in the flash via text and patterns.
