UPDATE - went in at the service center to check the starter ground cable.The cable was fine.
Right as i was about to leave,the exact same thing happened - a bunch of malfunctions on the screen(dtc,tyre pressure monitor…)and the car wouldn’t start or crank.
It was a huge luck it happened there,since they connected through the obd port and the issue seemed to stem from the car not communicating with the DDE. The mechanic had an idea and replaced the dde relay on the spot.He noticed the old one was extremely hot to the touch(maybe this is relevant).The connections seemes fine as well.
Main thing is - the car seemed to occasionally lose connection to the dde.

After changing the relay,the car started with no malfunctions and he ran the scan for errors again,and there were none,so hopefully this was the issue.
Since this seems to have been happening every week or so,I wil report back in a short while if i have any issues again.
