I agree something is strange with the vehicle.
These lines are the key to the problem:
Code:
[23:07:29.214] [2020-09-22] [<WinKFP Tool] 2089 PABD/CABD 06FLASH Programmieren 2538
[23:07:29.214] [2020-09-22] [<WinKFP Tool] switching programming mode failed 10FLASH, DIAGNOSE_MODE (ECUPM): ERROR_ECU_SECURITY_ACCESS_DENIED__SECURITY_ACCESS_REQUESTED
[23:07:36.562] [2020-09-22] [<WinKFP Tool] 2081 PABD/CABD 06FLASH Programmieren 2660
[23:07:36.562] [2020-09-22] [<WinKFP Tool] Authentification failed 10FLASH, AUTHENTISIERUNG_START ( SG-Schluessel ...): ERROR_AUTHENTICATION
During the flash process the programming station has to authenticate. The EGS will send a key to the programming station and the station then has to pass that key through a cipher and then returns the key. If it matches what the EGS is expecting the access is granted but in your case this is failing.
Since both WinKFP and xHP have the same cipher for that key they both get exactly the same failure response. So either the EGS has non standard boot sector code or there's some very wacky comms issues causing bad data but my feeling is that the latter explanation would cause problems elsewhere and not just at that one stage.
Just looking at the screenshots you posted it looks like that car has been updated at some point but the EGS has remained on its original firmware. The only other modules that have old dates are ones which probably have no updates available. The EGS should be much later than that.
