Where is this fluid coming from?
Almost pink fluid coming from the rear. Not all the time. Lifted the car up and nothing seems to be leaking. I did see a rubber tube between the diff and tranny pan. Kinda like an overflow tube of some sort. I think that's where it's coming from. Any ideas? Car is 98 A4.

It looks to me like it is a vent for the trans. Just finished a filter and fluid change on my A4 and the hose comes from somewhere on top of the trans then "T"s to a check valve and continues down to the front of the differential. Mine was also getting some fluid from there and would drip once in a while. Hopefully the trans was just a little over full and now that it is at the correct level it will stop.

I am going to have to go with C5FORFUN2 on this one, since mine is a manual and I don't remember seeing any hoses coming off mine when I changed the fluid. That being said, did you recently change your fluid?

Gave it a good work out today and no leakage from the vent tube anymore. So I think it was just a little over filled before. I also extended the vent tube down to where it's actually touching the ground ( need to shorten it or let it wear off) But at least if it vents some fluid it won't end up on the front of the diff.
