Im trying to update the transmission software on my w209 clk55 amg, followed all the correct steps and it started step 1 to download the file with the little bar thing going up, then lost internet connection and aborted.... Now when I try to redo it with even full internet it won't even connect to the server and says something along the lines of "data transfer failed" and won't proceed any further , have tried in connecting / reconnecting / rebooting and even sent a report to autel with no reply as of yet, please could someone advise on what to do as this was one of the main reasons I purchased this unit (ms908s pro) to be able to update all my cars software
Many thanks for any input or advice
