Systems Errors/Fault

[King1217]

Any help here would be massively appreciated. Car is a Mercedes A Class 2018 Automatic.

I was driving today and a load of messages appeared on the screen. Just a normal drive, about 50mph. I thought that's odd so stopped the car and switched the engine off.
Upon switching the engine back on all the errors appeared, the engine started but I could not do anything with the car (e.g. put it into gear, turn the windscreen wipers on).
It's not also not responding to the remote actions from the fob and I have to use the key itself.
As a sidenote I got a dash cam fitted three/four days ago, hard wired to the car...

The messages age;

"Active Brake Assist Functions Limited - See Owner's Manual"

"[symbol] Inoperartive - See Owner's Manual"

"Wiper manfunctioning"

I've cleaned the front bumper and rear bumper after a bit of Googling but still no luck.
I've tried to follow how to turn off the Active Brake Assist but the option showing online doesn't appear on my car menu.

Any ideas at all?

***Solved***

It was the dash cam. Halfords had put the line into the fuse box which for some reason the car didn’t like. He’s connected it back but with no Park Mode.

Thanks for the replies everyone. Appreciate it.
