Dash screen turns itself off then on.

[meldrew]

My 2016 model intermittently loses the screen when driving, and 2/3 minutes later turns itself back on again not good when sat nav is on.
The screen goes bright then blank, then re starts itself , and can occur every 10 to 30 minutes, the car still runs ok.
Anyone had this problem? or know the cause?

Hello. Une mise à jours de l'écran.

I would suggest a trip to the agent as your car may still be in warranty. If so it should be done free.

when my battery gets low the screen takes ages to turn on from ignition.
i needed a new alternator as it wasn't charging enough.
waiting to see if i need a new battery.

It only does it when the headlights are on. I think it is re booting, could there be a connection?

Could be but it shouldn't!

i've just replaced a shot 4 yr old battery.
if the screen reboots when u start ignition the battery is on the way out.

Advised by Citroen that the unit is faulty after 2 software updates, 2 months out of guarantee, quoted £900!.
My 2cv is 40 years old and never falters, is this progress.

Yup, it cost over £900, all replaced, working well now, but I am paranoid.
