Pictures! They can offer a better description. Someone with a PET catalog can give you a part number and description.

I have the same thing, I don't know what it's for either, it doesn't leak and doesn't seem to do any harm. It doesn't weigh much and I'm not sure it really serves a real purpose. It right above the power steering pump area correct? I want to know what it's for because I thought I was missing a hose when I first got the car.

It's a water outlet for the turbo cars. Most new pumps have a hole behind it. The plastic piece is blocked off for the NA cars.

what is it?

Exactly. If you look at a new or rebuilt water pump, you either have a block-off plate or an opening there (behind that nipple) depending on whether you have a na or turbo car. On the turbos, there's a water line that hooks to that - goes (I think) to the intercooler. It doesn't hurt anything. If it REALLY bothers you I suppose you could remove it (check to make sure this won't make your H2O pump leak before you mess with it) or hook a "dummy" hose to it or something.

my dads S2 has that nipple and hose.
And my car has the nipple only.

Whatever it is, don't touch it, you don't know where it's been.

That's right, the S2 has a hose connected there also. It goes to the coolant reservoir.

That block off plate is there so you can use an updated turbo water pump on an NA car.

On a turbo that fitting is part of the cooling system for the turbo, complete with thermostat.

Maybe I'll make it useful and route it to the coolant resevoir.

Maybe you should leave it alone.
