Here comes the new user feedback from one of the Foxflash users:
VW Polo GTI 2017 1.8TSI 192HP
Simos 18.1 ECU.
OBD VR read ok.
Hit "Read" and get vr file online.
OBD Write
ok.
Checksum correction with foxflash.
Simos 18.1 VR reading need luck.
There is no support for Golf 7 gti
engine.
golf mk7 vr was no problem, I went to do a customers mk7.5 — same
ECU — no VR available. Had to read and write in boot mode.

Problem: It’s a Ford Transit Custom 2017 with SID211 ECU, Foxflsah reads id ok but reading error. Any idea?
Solution:
Charge maintenance at 14V+.
Read and clear all defaults in your ecu and try. If not good repeat this and remove the positive connector on your battery for 5min and try again.
Normally reading is good.
