Are you using avdi online? I did the job succesful. 00 00 AA 20 is your dme isn, write it with avdi online. sync your cas dme and it wil be fine. If use avdi off line you dont see 00 00 if read or write but it is ok. than you put in AA 20 and sync cas dme.

Some times you need to put key out of car for a 1 min.
