This past weekend I did a timing belt package (timing belt, serp. belt, tensioner, pulley, water pump, thermostat, cam seals, crank seal etc.) on my 97 Audi A4 2.8 12v. Well everything went fine until I was putting the front end back on. I then noticed when plugging back up the wires under the power steering reservoir cover, that I was missing a wire to plug back in (see pic). I looked all around the motor, underneath behind tb covers (I looked for like an hour) and could not find anything. Anyway I went ahead and put the car back together and have been driving it for the past two weeks. I have had no check engine lights, and every option is working just fine. I know most people would say f!@K it, but it's bothering me. So I'm hoping one of you guys will recognize it, when you see the pic. Thanks!

it looks like it for the condenser

How sure are you?

Oh never mind that connector. I found that years ago in the location marked in the picture below. My best guess is that it's wiring installed for a feature not implemented in the US version of the A4. At least I think it's the same connector as this one:

I have one of those swinging freely under my car as well.

I think you're right moribundman, that is the exact same plug. I wonder what it is in Germany.

Could it be the wiring for the headlight levelers (manual up/down adjustment) that are a standard feature in Germany?

looks like it might plug into the coolant reservoir

I think you're right that is the exact same plug.may be some wiring problem is there.

Do you mean the sensor underneath the reservoir, because that one is plugged in. Also I would think that would throw a code, but I'm not sure.
