Could this be causing my P0444? what does your connector look like?

So in going through everything trying to get the dang car to start, I pulled the connector off the purge/breather valve at the front of the motor and noticed there is only one metallic tab in the connector. See the attached image.

The valve "male" end, has two prongs but my connector only has the one metal receiving tab in it... what does your connector look like?

That certainly is a problem. How many wires coming out of the back of that connector?

The connector pictured looks just like the one that goes to the oil pressure sender on the oil filter housing-it just has one wire. Are you sure you haven't mixed up those connectors?

I'm pretty sure I haven't mixed them up. That notch in the top of the connector is offset from center on the oil filter housing connector. I've tried to switch them but they won't fit over the opposite ones because the notches don't line up. The weird thing is that I never had the code before I did all this work, so i'm thinking if there is supposed to be another metal receiver in there, I may have knocked it out some how?

Sorry about the post I just wrote-it is wrong.

http://www.justanswer.com/bmw/7usnn-...tem-purge.html

The above link will explain how the purge valve works. There should definitely be 2 wires going to the valve-one for the power (12 volts) and one for the ground which is activated by the DME. The link will also help you to diagnose which wire is missing.
