Bricked the cas3 module during update so had to remove the module under dash. 2011 bmw 328i. No lights on dash and couldn’t communicate with cas. Used the autel maxi IM508 with xp400 programmer to attach apa106 cable and solder to cas3 module. The im 508 has built in colored schematics with great quality pictures. Soldering was hardest part. Retrieved eeprom and flash from Facebook. This just shows the steps I did under programmer function.
