Hey guys,
When I start my car, I hear a faint rattling sound coming from under the hood but near the front tire. It sounds like vibrating metal. When I reach my destination, I don’t hear the sound anymore. If I turn the vehicle off, then on again, there is still no sound. It only seems to happen when it sits for a long period of time. Has anyone ever had this problem or know what it might be? Thanks in advance…C-Bing

 

use search for control arm issue

 

which tire right or left
you got to try trace it when its
cold it could be anything
A.C clutch, alternator bearing

 

When I’m near the right side of the tire, it sounds like its coming from that side. When i walk to the left side, it sounds like that side. Again, i only hear the rattling sound when i start my car and once i drive for about 3mins it goes away. I went to the mall yesterday for about 20 minutes, when i came out and started my car i didn’t hear the sound. I think it only happens when its cold and sits for a long time.

 

My B5 always had a rattle like that on cold starts. You're gonna have to start it up and stick your head under the car to pinpoint it.

 

Will do thanks a lot

 

It may BE the hood. Check if the hood rattles. There are 4 adjustable rubber bumpers on the front which if you turn them out a bit will quiet hood rattles.
