Hoping someone here can shine some light on my problem. I purchased some Depo headlights from e-bay for my 01 A6 2.7T. Car had the factory xenon HID low beam headllights. The Depo's came with new bulbs, but required me to transfer the balasts from the old lights, which I did. Upon plugging the new lights in, the low beams (hid's) won't come on.

They worked before the swap. I've transfered the adjusters to the new lights, didn't help. Tried switching back to the old bulbs, didn't work. High beams come on, but no lows.

I'm going to trace the wiring on the old lights and compare to the new ones to see if it's the same. Any other suggestions? I wouldn't have to do anything with vag-com to restart the lows? I'm at a loss.

Thanks for any help.
