2014 ml63 gone mad - electronic issue

Hi AMGers

Recently I had an odd experience. Upon starting my 63, shifting into gear, accelerating, then entering s mode all while going 30 mph max all the warning lights lit up on the dash. Warnings in display that read do not shift, see dealer, traction control warning disabled, active curve system malfunction, presafe limited, blind spot inop, DDR inop, lane keep unavailable, etc(every warning you could get on the message display) rolling to next one every 5 seconds or so. Also the standard warning lights on dash all lit up. I pulled car over and restarted it and it has been fine since.

Any idea what caused this?

Freak thing or worthy of a dealer inspection? Took video of dash to show what happened if needed.

Thanks in advance for any input.

Don't try to self diagnose, that's what a warranty is for! Bring it to the dealer and see if they can recreate it. The video would be helpful for them I'm sure.

One of the connections in the fiber optic ring in the car is giving you an issue. All of the systems are connected through this ring network.

They found my issue by unplugging all of the different plugs one at a time to get the matching error codes... It was under the passenger seat or floor well.

It took MB a long time to figure out that this was the issue... Eventually they took my car back and made me a hell of a deal on a 2015. (Once they found it...it was fixed for good though)

ive seen this in a couple of other V8 MLs.....
Best of luck...

Did you happen to notice if your turn signals worked or not during this? I am having some of the same messages but it coincides with turn signals not operating or operating erratically.
