Hi

14 days ago bought my first mercedes, a nice 07 C350 with all the AMG package options.
But since day one it has had this fault, when i step on the gaspedal and floor it the esp/tirepressure warning comes and the car goes into limp mode. But only when i im flooring it, i can drive all day with no error.

Yesterday i found out that i dont even have to start the car to get this fault, i just get ignition on and give full throttle BING.... the error shows. as soon as i restart the car the fault is gone.

What is wrong can anyone help here. Could it be the gaspedal????

<Im from denmark so please excuse my spelling.

 

Ah, that sucks man. I've never heard of that issue :/

You might get better results over on the W203 thread though. I'd hit them up or move this thread over there since your model is a W203.

 

mine is a 204 not a 203 think i know my car a little better than u.
so if you will stick to answer my question, please.

 

Make sure your battery isn't going out, this caused the same problem in my dads 2010 c250. I've also heard something about resetting the steering wheel angle sensor or something like, but I'm not sure how to do it so hopefully someone else knows

 

charged my batt. today, it was low on power, i have tryed to reset steering angle sensor. but it made no diff.

But the way my car is behaving is a bit odd, I can recall the error without even start it.

Tomorrow i will have my shop update the cars software and maybe that will do the trick. and i will buy a new battery, just to be sure.

 

today my car got fixed and now it runs perfect, a new gaspedal did the job, no faults,

 

That's exactly what happened to me. Even scanning couldn't find the fault at first. When finally my indy shop saw a gas pedal fault, he changed that and no more errors.
Glad it worked out for you.

 

My bad...
