Lane Assist Error Message

Hi everyone,

For the past few days, I’ve been getting the message „Lane Assist not working“ on my DS7 (2018 model). Occasionally, I also see a message saying that the radar is not functioning, but this one disappears after a while.

Does anyone have an idea what could be causing this and how I can troubleshoot it? I’d like to try fixing it myself before going to the dealer, as I’ve had bad experiences with them in the past.

I’ve attached a photo of the dashboard with the error message.

Thanks for your help!
