–> tools discussion quoted from a bmw forum:

SanDiegoF12: Why is an BMW ICOM A2 required instead of just using the OBDII to Ethernet cable?

erdengurcan: ICOM A2 more stable than enet cable. For example: When you update ZGW via ENET, sometimes car stays on transport mode. But via ICOM it always come back to normal mode.

2real4u: A more technical reason is lack of DHCP server when connecting with ENET interface. This does not affect connection over DCAN, which is supported by BMW ICOM, but cannot be accomplished with ENET cable.
