Recently my BMW E-SYS ENET was out of work, thus I searched help on BMW forum and found some problems I may encountered when using E-SYS, here I will show you these problems and solutions.
When choose “Read Coding Data”, get this error:
Transaktions-Report: Aktion: Codierdaten lessen
CAS  [C271460]
File for “cafd_0000000f-005_022_007” not found! [C012]
Make Sure you have copied the SWE contents from PSDZData/SWE to C:/EsysData/SWE (You should have it in both the locations)
Open E-Sys and when hit connect get the pop up which has my VIN next to that radio buttion, but nothing shows up in the Target box.
More likely that the “dist” folders missing from your installation. The folders should be empty, but they need to be there:
make sure the folder names/directory is correct.
Ethernet Connection Problems
Disconnect and Reconnect
Read FA failed! Possibly there is no FA stored in the VCM. [C060]
There must be some OS or WLAN Adaptor setting that keeps the Wired and WiFi connections isolated or combined that is not set to isolate them.
