bmw e65 dde master and dde slave to cas sync problem

[exxl]

i have following problem, after battery disconnect and reconnect master dde and slave dde has got out of sync with cas, with abritres i resync master ecu but slave ecu will not sync, i tried also with inpa and rheingold but slave ecu will not sync.

car starts but works only on 4 cylinders since only master ecu is sync with cas, can somebody sync in dumps slave ecu to cas or repair to virign state somehow slave dde eeprom so i can try again to sync with rheingold or abritres.

dumps are attached
