Actually, it sounds like this tube is the C0 sample port, which is a
feature on K-lambda and up VW's.  It is normally covered by a little blue
cap.  Although the tube itself seems to be stainless and lasts quite well,
the fitting at the manifold seems to rot out, resulting in a neat little
hole that allows exhaust gas to bypass your muffler... :)

AFAIK, only Automagic VW's ever used EGR systems.
