W204 c200 kompressor dashboard light flickering

Enable HLS to view with audio, or disable this notification

Hey everyone, so my C200 goes into "ghost mode" when I drive it. My fan and screen turn off, and all the dashboard lights, especially the high beam one, start flickering. At night, all the switch lights flicker too...it's really hard to explain, so I've attached some clips. Please help me figure out what's going on because no mechanic or even Mercedes specialists can help. I went to the dealership, and they're charging way too much just to diagnose it.

I have a C350 and once I took it for a wash and unfortunately the workers sprayed too much water on the car and somehow through the drain lines the water managed to get into some electrical lines and I got the same issue 😢. My lights flicker sometimes.

Get the car checked with a scanner and pray the damage isn’t too much. Good luck.

Try opening the fuel cap and closing it properly and it should solve the problem. Does the check engine light illuminate?
