AUDI A4 B5 1.8T Immo Off - 8D0907557
« on: November 21, 2020, 03:59:59 AM »
Hi guys,
I am facing ignition problems in my car and getting DTC for immo from both keys.
I want to flash immo off. Can anyone tell me which is the immo Soic8 (I attached photos)?
I read and right to EEPROMS with Arduino from time to time with nothing to do with cars ECU. Will I be able to right the new values for immo off with Arduino or do I have to use special software to deal with checsum or stuff like that ?
Thanks all for the help

Many Thanks...
Do you happen to know if I need a special tool to flash it because it may have checksum like in ECU or I can just read and right it with any software possible of reading and writing ?
