Gearbox light on dashboard and gear issue

Has anyone ever had an issue with gearbox? The gearbox light is on and I can’t seem to be able to go higher than second gear … R is also no issue. Also not sure it is linked but the car refused to close with the key so had to do it manually… thanks for any insight.

 

Quick update … I disconnected the battery for a while and connected back. I did not drive but started the car a few times and the fault has definitely left the dashboard. Also the lithium battery that did not charge properly whilst plugged into a CTek is now going through the charging cycle without any issue … not sure what happened but I suspect ECU reset fixed both problems. Hopefully the fault does not come back when I drive next!

 

Thank you, the battery now fully charged and kept at 13.4v by the charger. I will get the F1 system checked as you suggested.

 

I drove yesterday. Issue has disappeared for now. I changed the CTek battery charger for a new Noco charger. Also the car has a lithium battery …
