2011 M3 CV idle problem

[edu09]

I just bought a new 2011 M3 CV and have a problem with the idle when standing at Drive after the engine is warm, it shuts off the engine, this happens only when the engine becomes warm
I took it to a BMW service center and they didnt do anything because there is no message on the computer showing any problem. I have read several forums and found out that there is a valve malfunction that may be the cause, anybody has have this problem so I can get some guidance as what to instruct the BMW people to look for as they only follow what the computer says (frustrating!!!)
Thanks for any feedbacks related to this issue

Couldn't you reproduce the problem? Do the 2011's have the power down at stoplights feature?

Yes, I am pretty sure this is his problem and he has no idea what he is talking about.

The car is working as it is supposed to. Isn't there a button to turn this feature off?

[edu09]

Yes thus car has the "A" switch that turns off and on the engine when the car is stopped at a light but I always turn this feature off when I start driving it so this is not the problem, the engine shuts off even having that feature off

Correct me if I'm wrong, but doesn't the car save your last setting? So, if you are hitting the button every time you get into the car, are you not turning it on and turning it off each time?

[edu09]

The switch has a green light that shows you when it is on, it turns on automatically every time you turn on the engine so I turn it off every time I am driving it because it is kind of unpleasant to have the car off on every stop, it is supposed to help you save some gas but if you bought this car the least you will think of is to save gas

Sounds like the switch is bustified.

what switch is everyone talking about ?? i have an 2011 and i'm not aware of such a switch..

[edu09]

The switch we are talking about is actually a button on the dashboard with an "A" and a circle around it, when you press the button you activate the on/off engine feature

after sep 2010, or people called it 2011.5 , 2011 m3 has the automatic stop start feature.. the switch is next to the sunshade...it is quite confusing at first. the lights light up actually means it was off. so if the lights does not light up. you turned it on so op that might be your problem.

lol, i thought this was a post about the idle air control valve issue.

[edu09]

Yes, that was definetely the problem, it was kind of confusing with the light on when the system was off, I was turning it on every time I was driving it and that was the whole problem, what is amazing is that nobody at BMW knew about this issue and they wanted me to authorize them a test drive or should I say a joyride just to check this problem, I had to find it out through this forum
Thanks to all of you for your help and feedbacks on this topic

To Evice:
I didnt get the manual with the car, I just got it after this problem, the manual was supposed to be in the trunk when I received the car brand new but someone in BMW took it out and forgot to return it
