My 2007 E350 has a problem with the passenger-side self adjusting HID headlight. The "old" headlight flickers and there are what sound like gears turning in the headlamp assembly. I've replaced the bulb, and it still flickers, but no gear noise. And without any bulb installed I have the gear noise. Any troubleshooting advise?

Thanks.
