Intermittent issue
2009 c63, 132.000km, about 80.000 miles, when car stays in traffic (gets a little hotter) all the lights show up in the instrument panel, no ABS, No power steering, speedo doesn't show speed, auto door lock doesn't work.
If cars stays off for about an hour, everything goes back to normal.
If I drive on a highway (well ventilated area) no issues happen, if it stays in traffic for a long period issue occurs.
Could this be battery? Alternator ?
The only other issue is a hard start in the morning

What does your battery drop to when you go to start the beast? Also can you hear the E fan running? "when its hot in traffic"
I went through something similar and the battery was cooked dropping to 8V during the start cycle but sitting 12.5V before the cycle was initiated. I had ESC error/ ABS issues and other ones but to me this sounds like power-related issues. I had similar issues with a GLK250 Diesel as well. From my experience, Mercedes does strange things when the voltage isn't high enough.

I would read this thread: https://mbworld.org/forums/c63-amg-w...-steering.html
Seems to align with all your symptoms 2 different scenarios but my guess is wheel speed sensor and a weaker battery is making it show up.
So might be worthwhile to get a new battery while your at it.

Hi all, I was unable to take it to the mechanic yet, but today after driving 1 hour or so, same issue appeared, one thing caught my attention, the brake lights stays on when driving, so I'm thinking the ABS central might be needing repair.
Any thoughs?

Found the issue
After testing every single sensor in the car, replaced the battery, issue is gone now!
Always check your battery first guys,replace for a new one, quality brand and @ the correct amp (95A)
2 shops tried to scam me trying to charge a lot to fix the ABS CENTRAL.
Thanks for the replies!

Hope you solved the problem. Yeah, the battery does have an important role on the overall "sanity" of the vehicle

Finally after 6 months I was able tô solve the issue!
Let me explain !
9 months approximately, I received and letter from the local vehicles administration office, regarding and outstanding airbag recall for my C63!
Called the nearest MB Dealer and proceed to schedule the service, couples week later on a very very rainy day, I picked up the car with the new frontal airbags, first thing I noticed that there was no image on my screen when using the Carplay,! immediately complained about it, but the rain was so strong I decided to comeback later.
After a month I took the car to my local audio shop to fix my Carplay, turns out MB messed with the switches on the Carplay central and image was gone, issued fixed!
After a few days when driving, had first issue, dashboard looked like a Christmas tree, no ABS, no power steering, no ESP.
After getting so annoyed with the issue, took the car back to the audio shop, asked them to remove the whole Carplay kit (to check if that could be the issue).
After having the whole dashboard disassembled, they found a ground cable from the kit loose and touching the car body!
The issue was this ground cable, it's been 2 months after having this cable soldered correctly never got the issue again!
Be careful with aftermarket upgrades, updates, LED lights and stuff like that, they can cause intermittent issues.
Thanks for the patience and replies
