Sound from 407 engines

Hello friends. When I started my car this morning, a very strange noise came from the engine. I stopped the car, started it again, the sound or something went back to normal. I wanted to shoot your video and ask you. Does anyone know what this sound is. [TUBE] _wfcu95-6ek [/ TUBE]

What is this sound? While listening to my pride was broken. I was expecting something like murmuring siren. I don't think it will be obviously such a video. Nevertheless, there are those who are masters and help us. Is it the first time? Then you said it was okay, no change, is it working properly like before?

sound came for the first time. I stopped and restarted. Sound stopped, I continued to drive normally. I threw the same video to the master. He said it could be from a crank pulley or balls.

I couldn't watch the video, but did it sound in the first run.

Now, when I watch it, I need to take a look at my coach timing belt, as if something might be stuck. the master's bearings, etc.

Thank you. I'll take the car to the master over the weekend.

You even run too much under this sound. If I was I would close the contact immediately :)
