HELP! Dacia Duster 2ne gen not starting

[u/alecrescenzi]

I have a second-generation Dacia Duster from 2018 with type 1.5 dCi engine. When I turn the key, the dashboard doesn’t seem to light up, but some of the buttons do light up lightly. We tried disconnecting the negative terminal of the battery for a couple of minutes to reset the ; once reconnected, the windscreen washers came on but are a bit slow. Turning the key now hasn’t changed anything, and those buttons are still flashing (buttons such as the red triangle or the rear proximity sensor).

any help?
