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

This flash is 100% same as what I read. I am assuming the data is correct unless there is something in the eeprom that is messed up. However, it looks more like a hardware fault.

Thank you for your help.
