i own a 2002 audi a6 2.7t.


underneath the antifreeze resivoir there is a loose tube hanging. it appears to be cut but i cant figure out where it belongs too. it is directly in the middle underneath the tank. is it supposed to be like this or is it loose and supposed to be connected? if so, where does it have to be connected to? can someone please explain where this tube goes???

i noticed this problem since i had a shop do the antifreeze flush.

thanks in advance. your helpful replies are greatly appreciated.

 

its a drain for overflow...
