Brake Problem!?!
It is telling me "Brake, Visit Workshop" What do you think is the problem? Is it just the pads are worn down? Also it has seemed to effect my Keyless Go. Sometimes when I try to start the car it just turns on the Radio on the first push and the Accessory on the second and turns off the car on the third.... like what happens when you hit the button without the brake on. Any ideas?!?

I had the problem about six months back. my mechanic told me it pops up when you overheat the brakes, i had on the track the previous weekend. it turned out to be a $9 brake switch behind the brake peddle.

It is the switch going bad, but why from heat? It is a damn fly by wire system. I've had the overheating warning come on many times (not since the Evosport rotors and porterfield pads) and it was never an issue with how the car ran. Hopefully the switch is under warrany, if not be happy it is $9.

No relation between the overheating and the switch. It just so happened i overheated the brakes the weekend earlier. The mechanic thought that might be the culprit for the "brakes, visit mechanic" warning, it turned out to be the switch.

Yeah I'm pretty sure I'm out of warranty so I'll be doing the fix myself. So where is the switch located? Also does anyone have a part number or actual technical name for the switch so I can go to the dealership and buy one. Thanks everyone for all the help.

Could be a couple of things. Including the SBC hydraulic pump(the pump that stops the car for you). The pump reaches it's "service threshold" and needs to be replaced.
For those who don't want to spend any money and wait untill something happens, guess what... it's covered under warranty!! Mercedes applied an extended, unlimited mileage warranty to the SBC hydraulic unit for 10 years.
To me it would be worth it to stop by the dealer and see if the pump's on it's way out and have it replaced under warranty.

Oldschool, I had the exact same diagnosis. Bad pump. Replaced under warranty a few years back when this happened. Thank god, cuz it isn't a cheap fix.
Take it in. I'm betting your SBC pump is failing. Don't clown around with your brakes! Brake warnings are one of the few things that'll have me in the dealership on the same day it pops up!
