Mercedes-Benz EPC: Long press the trunk lid key on the key to open the trunk, and long press the door opening key to open all doors and windows at the same time. But the premise of this function is that you should be close enough to the car, about two meters.

BMW ETK: Every BMW has a vehicle configuration table, also called FA file. Every configuration under FA file is what we usually call VO, and usually a 3-digit code represents a functional configuration. A piece of hardware does not necessarily have only one VO, sometimes a piece of hardware is defined by several VOs.

In addition, BMW's ETK vehicle configuration table inquires the factory configuration table according to the last 7 digits of the vehicle VIN. Connected vehicles read, FA files of E chassis are stored in CAS and FRM (or NFRM) modules, and FA files of F chassis are stored in CAS and ZGW gateway computer modules.

Extended data:

When BMW ETK checks or modifies VO list, it is necessary to avoid conflicts. There can only be one main engine in the same car. If the 663 small host is in the VO list, you cannot add the 609 large host.

For example, VO698 and VO 702 in dvd area can't exist at the same time, and some VOs only in American regulations can't appear in China standard cars. Other configurations only appear during certain time periods.

In addition, if the wrong VO is used to match the vehicle, if the power system is involved, it will easily lead to failure. For example, it is very common to code American standard cars with standard X5 VO, which will easily lead to 4X4 failure and ISID failure to delete errors.
