Throttle issue
Hey all I did a search for this but couldn't find the answer. Last night when i was backing up my M7 and i was getting a weird noise when i would blip the throttle and it would go away but it almost sounded like something rubbed together and stopped. So after i stopped i put into Neutral and did it again with the same result. It only happened if i hit the the gas. If i really lightly hit the gas this doesn't happen.
I think a trip to the dealer is in order because something isn't right. I will try to get an audio of the sound to see if someone can identify. But it occured between idle and 1000 rpm, after that its gone. I hope its not some major issue but I am not sure if its powertrain related but its still under warranty.

If the dealer can't replicate the sound they wouldn't do anything. It's sometimes better if something actually breaks and disables the car. I would ask to go on the test drive with the mechanic so you can point out the noise. It could be something other then the drivetrain.

Had another opportunity to look it over. It is a very apparent noise that happens every time I blip the throttle harder than feather pressure if that makes any sense. Its hard to explain that part but it sounds like it may be the throttle valve possibly sticking or making contact with something as the throttle is initially opened up, but like I said goes away. Can something possibly be gunked up.
I am going to take it to a dealer. I have been sidetracked with my home purchase so my time with that and working has my schedule a little tight.
Since I am located in Columbus OH now I am thinking of taking it to Coughlin. I originally took it to Dave Gill because I have forgotten about Coughlin lol when I first arrived for one of my free oil changes.

If you had a video/recording of it, it might help... I think it sounds like you are talking about the intake of air that happens if you stab the throttle when it is cold, you will hear the vacuum sound before it revs up... which is normal. I have noticed it is loud on this car. I would still take it in and let someone at the service center hear it, if you are unsure though.

I just replaced my air filter and cleaned the butterfly valves and the surrounding areas with carb cleaner. Never spray anything into your throttle body unless you know what you're doing. The best method is to spray carb cleaner on a lint free rag and wipe everything down. It was pretty filthy in there so I'm glad that I cleaned it. You may have a piece of carbon or something stuck up in there. Good luck.

Your absolutely right, i need to get a video of it. I just hope I can capture that sound on the phone. But I have had the car over 2 years and just noticed it a few weeks ago when i was backing into a spot and i would feather the pedal as I was backing onto a non paved surface. I did lift the hood and it is clearly coming from the engine compartment.
It has sat most of the winter. I think I have driven it 7 days since November. This is the first year I had to deal with snow in 10 years since I have been in Vegas where it only snows on the mountains.
I will be making contact with Coughlin shortly.

Having the same type of issue. Just started after they installed a software patch. Mine is occurring when I hit it slightly hard from a cruising speed and now when I ease up on the accelerator. Not very loud but noticible to me. Not a clunk, not a squel but more along the lines of slight screach. Agree it is hard to explain.

This is what I am referring too... listen to the slight "chug" when I stab the throttle...

. I will take a video tomorrow while and compare it to what i heard from mine and see. It does very well sound the same but would like to re-attempt mine to be sure. Thank you so much for this video 
Is this a major issue or is it just a bug in this car

Anywho to update you. I was able to capture the video and i compared the samples and it does sound the same. I captured it with my S5 which is probably considered ancient technology the way these damn phones come out.
It is limiting me in sending it to my email so i will re-do it with my ipad and then connect and place it here.
I drove the car about 30 miles that day as well and i didn't hear it as drastic when i was driving. Heard it faintly on occasion but under normal start from stop didn't hear it. Just when i rev the engine. Although you guys say its normal I will still when i take her for service have them look at it just to confirm it isn't something different.
Thanks guys for the responses. I will continue to keep this thread updated

I am still trying to figure out why I am just hearing this for the first time now 2 years into ownership.

The noise is more prominent when it is cold and warming up (rich condition), then it goes away a bit. If it seems abnormally loud, you could have an opening somewhere around the air box (maybe not sealed all the way) that is amplifying the noise. Have you had the air filter replaced or checked lately? Could be somone didn't close it up correctly.
