Hi all

I just had a weird experience on a car I bought a couple of weeks ago (c300 2019 w205).

I hopped in the car as normal, and as normal, i flicked the dynamic roller down wards toward eco, and turned off the start/stop function.

A couple mins later I realised neither had worked. Tried again, nothing. Then noticed all the buttons to the left of the scroll wheel are not working, and the buttons on the center console are hit or miss.

Also noticed a red blinking light on the center dash, next to the airbag light.

Reset the system, etc etc, nothing worked.

What on earth is going on? Had anybody else had the same thing?

Thanks so much in advance to anyone who can help.
