Q: Audi 2006 A6 Bi-Xenon dynamic headlight shutter malfunction
The adaptive light warning signal lit up on the dashboard. So I did a bit investigation. This A6 has bi-xenon dynamic headlights (item# 4F0941030BD). The VAG shows a fault code: 02747 - Solenoid for Bi-Xenon Shutter; Right. 011 - Open Circuit. I opened up the enclosure from the engine side and confirmed that the passenger side lamp shutter for Hi/Lo beam is not working. It is not stuck as I can move the shutter manually once I take the bulb out. However, there was no shutter moving or the electrical motor sounds on the passenger side; these mechanical sounds were present on the driver side when I engaged them. The bulb and ballast are functional. I did not see major wiring defect, but the view was limited as most wires were already wrapped.
So, based on this information, should we go directly to getting the whole headlight assembly replaced? Please let me know how you think.

If this is a solenoid activated device, test the solenoid (winding resistance in ohms, function, etc.). If the other side functions, you can compare the results. The code seems to suggest you will find infinite resistance in the winding of the solenoid. If the solenoid is available separately, obviously just purchase that component but if it is integral to another assembly, you’ll have to buy the assembly.
