You have CAS4 5M48H selected in X-Prog, but the faulty CAS4 is CAS4 1L15Y.
I think in X-Prog you need to select CAS4 1L15Y, which has EEPROM and FLASH.

in xprog version 5.5.1 and 5.8.4 from this forum there is only cas4 5m48h option.
there is no 1L15Y version to choose ???
Has anybody here an xprog version with cas4 1L15Y ?????
Many thanks...
