But I think the options now would be:
- Bulb is offset & not hitting the angel eye ring properly
- FRM
- Say f it & get new headlights

I'm not even sure that needs coding. My 2008 has a setting in iDrive for DRL that turns the angel eyes on. I think the voltage provided to the halogen bulbs that are used is low to increase longevity since they're DRL - maybe like 10 or 11 volts - not sure. However, there is a setting if you know how to code the cars, which will increase the voltage to the DRL bulbs so that they become brighter. IIRC I did this a few years ago to make them look brighter like the newer cars with LEDs.
Other things to note:
1) One of the two rings is always brighter on each side because it's closer to the bulb. That's just how BMW designed it.
2) LED bulb upgrades or the coding to increase the voltage will make things look more consistent. Both rings will be brighter and more like modern lights.
If you posted a picture of your car in the original thread, obviously someone has replaced the bulbs if the DRLs are that yellow. I know you said you switched bulbs and ballasts, but are you sure you switched the correct ones that drive the angel eyes? The ballasts have nothing to do with this IIRC, just fyi. If you definitely switched the correct bulbs around from side to side and it's still a problem, then yes it probably has to do with how the bulb is sitting or maybe something is phsyically broken in the light itself. It wouldn't hurt to post a picture of both headlights so we can compare and make sure we understand each other.
