Title: Simple Change? Post by: daczone1 on February 23, 2025, 07:24:25 AM I have a 2001 Audi tt 1.8 and I bought WB ECU (2003 TT) and a harness and WB o2. Can I simply remove IMMO and use this ECU as is? Can I remove IMMO myself? I solder together a cable... from the form ODB to a spare ECU connector but confused about BOOT mode.
Title: Re: Simple Change? Post by: _nameless on February 23, 2025, 06:20:26 PM What cable do you have exactly? To disable the immo you need to read out the eeprom, I think there are 2 or 3 on this site that will work with a ft232rl based cable. You can also use a chip burner to read out the eeprom by using a chip clip or unsolder the chip and dump it directly. After you get the read you can flip a few bits to switch off the immo, you have the immo status on is set as 1 and off is set as 2, you need to do the backup page as well. Update the checksum blocks by removing 1 from the existing values and you are good to write back the eeprom.
