Solve Autel IM608 BMW CAS4 5M48H Chip Unlock Failed

 Question: Anybody come across this issue? I’m trying to read DFlash or PFlash Cas4 on an F10 BMW  5M48H -with Autel IM608 outcome it reaches 7% and then says chip unlock failed. (I’m using xp400Pro).

Solution:

These soldering points don’t look good.
Check wiring diagram on im608

you also have not removed resistors and a component marked with Ts.

Good going for using a module from a breakers yard, look up godiag test bench, no need to solder then

Or you can go Yanhua Mini Acdp and you’d already be done, no removal of anything.

 

Feedback:

It turns out I have to remove a few components (T1,T2,T3,T4) before it can be read, and re-solder them afterwards.
