I found this in the cat on the turbo side.

It's a little bigger than a quarter. Flat on one side and has a 1/4" stud centered on the back side that sticks up about a half inch and a small triangular stud on same side.

Any clue what it is???

The part # says 18 16

 

Here are some photos

 

that happend to me its you wastgate flap gona need one of those. turbo that is.

 

That's a bummer, but it's a good excuse to upgrade!

 

Wastegate flap or an old beer bottle cap

 

I don't suppose there is any way of just replacing the wastegate assy, is there?

 

not unless you buy the whole exhaust housing, or buy a junk turbo and cannibalize parts from it.

props for using search!

 

I will see what I can find. Thanks

 

*****. Haha, thats like the worst place to find something. Either way you'll probably need a new turbo because either A.) Something came off the compressor or B.) Something went THROUGH your turbo and into the cat. However impossible that is. Jeez

 

I suppose there's this solution until I upgrade http://forums.bimmerforums.com/forum...d.php?t=467495
