ok !
I now understand what you know by lifted
I have already done a immo off on these type of physical lifted chipped ecu, in my case its was APR chip.
the big black wire is your ground to the pin 24 ?
I will write you the exact procedure to bootmode the ecu
1-Ecu need to be power OFF
2-carefully apply ground at pin 24 ( the spot with the red circle is more safer, you don't want to short pin 24 to the pin aside)
http://wiki.obdtuning.com/images/thumb/9/97/VAG_ME_7_Platine1.jpg/800px-VAG_ME_7_Platine1.jpg3-hold the ground at pin24 in the same time you power on the ecu
4-leave the ground 5sec
5-remove the ground
6- done you normaly are in boot mode
