XJ (X351) - AHBA and TSR issues

[Scousejag]

Hi all - hoping someone can help

I’ve noticed that my AHBA no longer works; I leave for work at 3:30 in the morning via a country lane therefore I know it’s definitely not working. I’ve checked the setting in the menu and the stalk is set up auto - to no avail. I have noticed that when I get in the car in the morning the green auto light symbol flashes on and off for a period - not sure of this gives a clue

Secondly - and possibly related - the traffic sign recognition works intermittently as in the option in the menu is sometimes greyed out. On the occasion it’s not greyed out and I select it it works fine until I turn the car off. I then have to re-select the setting (if it’s available) when I restart

Lastly (and I need to check this) I’m fairly sure the headlights (on auto setting) are permanently on

could it be a battery thing?!

any help would be greatly appreciated
