Stan, thank you for the welcome and the advice, I will take care of it as soon as possible... even if I think the problem is elsewhere.

How did you get on? I’ve just bought a very similar cr with very similar problems! Current > FFRR 2018 3.0 SDV6

none of these malfunctions are related to TCU.

Does anyone know if the Gap tool can reprogram the TCU? Got - 2017 SDV8 Autobiography in Loire Blue

Same problem as you on MY 19 I have an iidtool and asked gap diagnosis, they couldn't do it yet, it was 1 year ago. I have "wi fi unavailable" SIM card impossible to uncheck "data unavailable" and a "G crossed out" at the top right of the screen. I tried to remove the fuse from the TCU for 48 hours to reset but it didn't work. The dealer offers me to uninstall and reinstall the software. I haven't done it yet. |

I think an uninstall/ reinstall might be the way to go. I found these when searching for LR TSB's:-
