Odd startup noise.

[spoolin]

I have owned this car for a few weeks now and love it after selling my supercharged e36 m3 and 135i. The car is a 2011 with 75k miles. I am very familiar with most of the normal noises this engine makes and love them, however, I get a strange noise at start up. I can only describe it as the engine sounding like it is running dry for a brief second until oil pressure builds up. This is the only abnormal noise I have noticed and just wanted to see if anyone else has experienced it. The noise only happens at start up and subsides after less than a second of running time. Thank you.

Spoolin, your video doesn't seem to be available?

I'm assuming it's the timing chain tensioner. It does it on mine too.

Video is set to private

1- Your video is private and is "not" working .
2- I'm almost 100 % sure that's your start up noise => http://www.m3post.com/forums/showthread.php?t=996069
3- Take your time and read the thread of the link .
4- Let me know if this is your start up noise .

I apologize. I made the video public. I have read the thread mentioned above and do not have that noise mentioned. It is not a metallic clunk but instead a noise that I can only relate to my aforementioned description. I searched pretty well and listened to most of the startup videos I could find.

You don't need to apologize , that's no problem .
First I thought that you had the clunck noise when your S65 was cold at start up , because many S65 owners have this noise .(your video was private)
Sorry for that .
For your video now...It's working , and so I was listen to it..
And your S65 sounds just perfect , no abnormal noises , it sounds exactly the same as mine .

Sounds just like mine during the cold start cycle.

Yup. Timing chain tensioner.
