Hi.
I have a 2009 M-B C63 AMG. Some time ago when I was cruising at about 50mph and hit the gas (all the way) something strange happened. Message showed up "Traction(icon) Inoperative See Operator's Manual" (photo below) and car started to accelerate very slowly. When I restared the engine everything came back to normal again. It already happened to me few times after that. What is going on??? Can somebody explain to me???

Did you ever think of reaching over to the glove box and as instructed read your manual----before I comment, what did you learn or are you still in a daze!!

dvd_mi

Yes, I looked. I went through the whole manual. Could not find anything there. I bought the car couple weeks ago, so I am still new MB dashboard messages.

Plutoe

Post the VIN!!

The search actually works well here. Could be anything. Need to scan the ESP module to find out what caused it.

I checked those, but none of the threads shows dashboard message I am receiving.

Nevermind

As noted the ESP control module moniters about 15 systems and obviously one is wheel speed another is side to side acceleration and forward\rear acceleration,therefore when you floored the car the very sensitive ESP sensed a wheel speed and or a lateral direction change and engaged the ABS system slowing the acceleration.---At that point your dash lit up and you received a message bla bla----which actually means use your R or L multifunction buttons to reset. It's saying you created an unsafe condition bla bla

To prove the point turn the ESP to passive and you will get a constant yellow triangel-----now create the same previous contitions---what happens and do you get a message

Overall I would say that you do not have an issue, the ESP is simply doing it's job or telling you to turn on the ESP and let it help your driving conditions!!


PS: I also noticed that in your screen shot the ESP was off----was it off at the beginning of this opus!!

dvd_mi

No, it was not off. The dashboard was just like when you start the car. All lights and messages came after I floored the gas pedal.

I had simiar experience and it was a faulty gas pedal. Replaced and no more inoperative traction control.

Though i think you still need to find out what code has been store to really make it sure.

If this happens in often it could throw a permanent code. Or you can check right awa while is inoperative.

dvd_mi

But as soon as I restarted the engine that message was gone. Is it stored somewhere??? Do I need to go to the dealer to check it, or will I be able to find it myself???

Jasonoff

Just like ugly fat girl you hooked up with at a party because you were wasted. Just forgetaboutit...

dvd_mi

K, thx.

DidierD

OP, was this issue ever resolved, I have the exact same thing with my 62 plate Sedan

dvd_mi

It came out that gas pedal was faulty. Just like jay_rick, I replaced it and problem is gone.

DidierD

Great thank you very much, thread is 3 years old wasn't expecting a reply!, I'll give it a go, do you know if I can just replace it myself plug and play, or does it have to be reset etc in a more advanced way? I wonder if it's anything to do with the throttle position sensor which I believe is integrated into the accelerator module, could be wrong.

dvd_mi

It was done by my mechanic, but i believe it is plug and play. He didn't say anything about any programming or adjusting. He told me it was same part as for regular W204 C-class. I think it was about 200-300 usd just for the part. Also before you do anything go the dealer or good mechanic to verify if it is the pedal. From what i know that gas pedal issue is pretty common in all W204's.

DidierD

Yeh I'm booked in for Thursday however I didn't get any engine management lights so I doubt any codes have stored so not sure how they will be able to fully diagnose but I will leave it with them, was tempted just to do it myself.

Also was hoping it wasn't that expensive! Either way thanks for the advice, will see what the mechanic says, they're a well reviewed AMG specialist so hopefully they can sort it.

you done good! Most people don’t search and just post new threads. Best of luck with the new pedal.
