How to Solve F10 BMW chip unlock failed by Autel IM608

Question: Does anyone know this problem? I’m trying to read DFlash or PFlash Cas4 on a F10 BMW 5M48H – with Autel IM608 result it gets 7% and then says failed to unlock chip. (I use xp400Pro).

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

They also didn’t remove any resistors and a component marked Ts. Good for using a module from a breaker yard, look up the Godiag test rig then you don’t have to solder anything.


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