ESC Inoperative Error
I received the ESC Inoperative Error (Orange Light) about 3 times since owning my vehicle. I believe in all 3 instances, I was pushing the pedal and accelerating pretty hard.
The car basically feels like it hits a wall when this error comes on. I have to pull over to the side of the road and restart the car. All then returns to normal.
This has happened to me 2 times on dry road and 1 time on wet road. I guess the wheels slip when accelerating too hard thereby causing this error?
I'm not sure, but it's dangerous for the car to just suddenly slow down like that when the error does occur.

I get the little triangle warning light that flashes sometimes when I smash the pedal, but I've never felt a change in response and no light has stayed on.
Have you had it checked out?

My car is Renntech tuned so I'm not sure if that makes a difference with what is happening...

Not sure about the tune, but it seems you only get the error when ESC has been engaged due to some slippage. That would seem that there is a fault in the ESC that isn't apparent until it tries to correct or compensate for the traction issue. To me that means that your traction control is bad. The system should engage, make its adjustments and then disengage but yours get stuck and gives you the error while you're stuck driving in limp mode. Don't know if that makes your car less safe to drive in poor traction situations or not but you should look into it.
Do you have the equipment to reflash the stock tune and test to see if the same error occurs? If you don't get the error without the tune, then you know there must be some conflict with the tune when ESC tries to do it's thing. If the same error happens, then your ESC could be bad.

Also, do you know if our cars warn us if we have a low battery? This is my first Mercedes.

Supposedly these computer save error codes in a log. When I bought mine and had the PPI done at the dealer, they gave me a list of error codes from earlier years. Not that it was much help as they didn't really take the time to help me interpret them and the car was fine anyway.
There is no warning for low main battery. I have to jump my car a few times already. Comand will give you a warning if you continue to use it after the car is off. However, I gotten that warning and had no issue with starting the car later on. My battery escapades are documented in some other threads on here.
There is an auxiliary battery in the dash for the electronic transmission shifter. The car does give a warning to replace that. So far (knock on wood) I haven't gotten that one.

If you have any independent mechanics around, you might be able to talk to them about the issue to see if they can help at a lower cost.
I know where you're coming from - if the light isn't on when I take it in then I am usually wasting my time.

Yep, I'll check that option out. Yes, wasting time + money for them to say "nothing is wrong".

P0872 (0872) Fault of function monitor in electronic accelerator (p2638).
I know from prior research people with this same esc inoperative error had it fixed by changing the accelerator pedal (gas pedal) or steering angle column sensor. It seems the code above points to the pedal? The tech didn't know offhand so he said he would do some research and get back to me.
Any ideas or thoughts on the code? I also read that the mass airflow sensor could play a part...

I believe this has something to do with the sensors on the accelerator pedal. I've got this problem once before and the dealer did something to the pedal. Subsequent to that, the error never pop out.

2014 E63S; AMS 100 octane ECU dyno tune; EDOK TCU tune; BB intakes; sprintbooster
Sprintbooster will cause this
Do you also have that?
If not you just need a new accelerator pedal ... Should be under warranty

I think the pedal is the solution too. Now I heard that some people buy just the pedal vs the pedal assembly?? My car is 2010 year and 58000 miles. It should be out of warranty. The pedal was changed by a dealer back in 2012. I'm assuming for the same issue. I don't think I have a sprint booster.
Sprintbooster will be a small piggyback looking cable to the side of the pedal... It can be very discrete

If steadfast in replacing, accelerator pedal is part # 2043001104 (confirm with VIN).

How hard is this to do myself? I'll look for a YouTube video.

Did replacing the pedal work for you? I replaced mine and took it for a test drive at night...went over a hump in the road and esc inoperable message appeared again...took a right turn with little deceleration, message appeared...
