Broken black plastic tube under MAF

[Silver_TT]

Anyone know what the broken plastic tube is that I have circled in red in the attached pic? I pulled the MAF out to work on my alternator and noticed this directly under it as you can see with the engine in the background. Is this something I should be concerned with?

This is the exhaust vacuum for my sport exhaust <insert raspy growl here> ...

Not really sure if it's something to be concerned with since it's presumably been broken for some time (didn't notice until I pulled the MAF off to get into the engine to do some other work) and my car seemed to fun just fine -- either way, I am going to replace the tube.... If it's there I assume the Germans put it there for a reason.

This could very well be the vacuum lines to the PSE, but it is not the OEM path for the lines.. The default position is loud, so if you don't try to switch it to quiet mode you might not know this is leaking. I would reconnect it as it may allow vacuum pressure to leak out of the system. There are components that are supposed to prevent this but I would fix the connection.

Thanks Dharn, I appreciate your input (and I say that generally speaking -- one of your posts a while back helped me fix my passenger seat motor as well). I will look into this further. I also thought that the path for the lines seemed very peculiar.
