Hi
I am working on a 7 Series BMW with a CAS4 mask 1L15Y.
Car lost ignition and we found a CAN filter inside the unit. I removed it and tried bridging the pads where CAN BUS driver used to be. Anyway, there still is no communication with the module at all.
Now, I read EEPROM and FLASH from the 1L15Y MCU and wonder if anyone could check if they are good. Eeprom I can see the VIN, mileage, ISN, 3 keys etc. so probably good. I am not sure about the flash.
Basically, if anyone could have a look at the files and confirm they are alright - I will be very grateful. It would mean the hardware issue and I would just go and get a 2nd hand CAS4 and inject the data into it.
Many thanks
