VO = NCS -> ad $540 -> FA_WRITE in CAS and FRM. (添加VO，帖子里的车不同，E84这个总成貌似是$544)
Read ECU Kombi -> backup file .trc ( for restore ) (这里是备份，基本无所谓)
Read ECU DSC -> backup file .trc ( for restore )
Code in expertmode -> Kombi and DSC. (我猜其实就是执行sg_code命令吧，把添加VO后默认的设置刷进去，参考刷蓝牙，只是模块不同)
reset angle sensor in DSC modul. (这个是针对仪表盘报错的复位，貌似很简单，启动，方向打到最左，再打到最右，然后熄火，油土鳖上有视频https://www.youtube.com/watch?v=5iXQDSOZOt0)
