Vehicle is an 02 Base A4 Convertible and while I was changing the plugs I removed the valve cover plastic dress up shields.
Sitting between the manifold and the top edge of the passenger V.C. I found this. It looks like a suspension bolt but the head is 1/2 inch not 13mm
Anyone who has an idea where it came from please chime in
Thanks

I’ve had my motor down to the short block and my entire drivetrain apart, and I only remember those rounded bolt heads on the bell housing bolts. and every bolt I touched was metric also.

OK, now comes the intriguing question. What was the previous owner doing removing this and are there any other loose bolts? I’m definitely putting this on the lift before I drive it again
Thanks for sharing and saving a potential disaster
More like the torque tube to bellhousing bolts not seen thus far.
I’d say it’s the one at 1 o’clock that most neglect to replace as its tough to access. You won’t see it though with the exhaust h-pipe still in the way.
That bolt DEFINITELY sucks and even with the rear cradle lowered it takes a series of extensions and swivels.
I know because I left that one out. And I got a squeaking sound at idle mostly that I chased forever exhaust related. That missing bolt held the wiring harness in place and that metal started rubbing on the bell housing making a vibrating squeaking noise that finally I tracked down. That was a few weeks of frustration and that missing bolt was it. Installed it and my world was correct again.
