Weird HID Problem

[RickyB8A4]

I bought my headlights and installed them my self. everything was working fine until my passenger side bulb stopped working. So I narrowed it down to the bulb so I bought a pair. They arrived today and installed them. So the passenger side works now, BUT now my driver side beam isn't working. I had 2 spare bulbs that are working fine, I even switched them around a bit to the passenger side. But on the driver side they do not work at all, however the DRL and turn signal works. Please help!

I am assuming you have a VCDS that is your best bet. Are these OEM ? Any fault lights make sure everything is connected properly if the bulb is still not working your ballast may be out.
