UPDATE:
IPC update info:
Ensure you backup IPC config before ANY updates!!
Also make sure car attached to a battery charger and also that the laptop is on mains power!!
It takes a long time (even with an official UCDS cable) to do the update!!
After update you will have to re-select some options in IPC module (drive modes etc.)
Take your time and hopefully IPC update goes smoothly!!
Here is a list of the updated software files (UCDS offered to my car) – RS Focus MK3.5 2017 – UK build:
G1ET-14C025-BE
G1ET-14C026-ABG
G1ET-14C318-ACE
G1ET-14C026-BSE
Good luck!!
