do you know if the 1653 is pre-Dieselgate and the 3201 is Dieselgate?
3201 version firmware release date is 2016-03-08 13:15:01 and it is current version till now.
1653 is first factory release for 2015 (first DG year) model year and maybe there is no preDG version firmware for DFUA engine at all.
, can you help me implement NLS and LC? Obviously paying
