    If you have INPA go to DDE and than select CAS-DDE sync menu.
    There is an option for reset sync (F1 button ) and store sync code (F2 button ).

    You need just the: RESET SYNC CODE EWS-DDE (F1 button)
    Then just switch off full ignition for 15 sec and then start car

    I also uploaded your ews eeprom as factory reset,so you can try writing this file and syncing again,if no solution works.

    I do same but with ISTA-D, it says sync is ok after done, but still no crank and 4A42 error still present.

    What to do with EWS reset? Write and then make new transponder and sync? Can I use the actual keys?

    I have solved same problem. Disconnect battery, read ews dump and write again with ak90, connect ews back in car and battery and car start fine.

    Ok news on this car. I just see somebody take out EWS fuse on this car, this is already solved. Other thing is with Bram380 files, I see there are no checksum error on DDE ISN, and the ISN is the same on EWS file, so I write those files but still no crank and error 4A42. So I know I´m pretty close to solve this car but still no luck.

    What is the next step?

    Thanks to all who helped me.

    Hi,
    No crank it mean no correct key detected by ews.
    Possible rolling code problem.
