No, SKU FTA-KM-FULL should not be represented as supporting full Mercedes-Benz FBS4 key programming. The PolDiag full set is mainly advertised for Mercedes FBS3 functions, including EIS/EZS, ELV/ESL, ECU/TCU work, key generation, and all-keys-lost on supported FBS3 systems. UHS lists Mercedes functions such as OBD/IR work, all keys lost, and unlimited key calculations, but does not clearly list full FBS4 key programming support.
