Hello. I know E65 / E66 BMWs has Integrated Supply Module and it fixes random not starting problem in the car more than replacing starter alternator or battery or battery cables. I want to know what is the equivalent Module that bmw used on e9x m3 cars? Does anyone know the name of this part? I am not sure it is in the DME Box under the hood or i don't know which one it is. Maybe CAS? Need help!

Here is the Voltage and BUS system of e90:
