Hello,
I am trying to read flash from engine controller from BMW.
Wiring diagram says that i only need APA107 and external 12V to do it.
But after 5% IM508 shows "Chip no answer".
ECU is OK. It starts engine normally.
I can read it with another device without any problem.
Read ISN without any problem.
Only my Autel doesnt want to read it.
I tried to connect it to my laptop and use xp400 Pro with it but same "Chip no answer".
IM508 doesnt read ECUs ???????
