Breather pipe part number S4 B8

[Crowdie]

Hey,

I've managed to snap a breather on my B8 S4. I need to replace the part but am struggling to find the part number.

Does anybody know what this might be?

Thanks

I think that's the secondary air injection pipe.

That looks like the one! £100, expensive mistake. Also looks like it will be very difficult to replace. Thanks for finding it, I had a crawl through some parts databases and came out with nothing, this looks identical.

Never heard of secondary air injection, dont suppose you know the purpose?

It's used on start up to heat up the catylyst faster.
