Question How to replace Xenon light bulb?

The right Xenon light bulb in my 2006 330i burned out (after fading to red). Dealership quoted me $400 to replace it (or $800 for replacing both to match the color). So, I have a few questions:

1. Do I need to remove the wheel to replace the bulb, or I can do it with the wheel on (through the flap inside the wheel well)?

2. What parts specifically do I need to remove to access the Xenon bulb?

3. What is the difference in longevity or quality between Xenon bulbs on eBay at $50 for a pair (made in Korea) and OEM bulbs?

According to the Bentley manual the "trapdoor" only works for halogen headlight set up..for Xenon system you have to:
Remove headlight fuse...xenons have high voltage and are dangerous!
Remove wheel housing trim.
Unlock headlight bulb cover retaining clips, remove cover.
Hi beam halogen is just plug 'n play..grip socket and pull out...
Low beam Xenon:
Detach harness connector for xenon bulb ignition unit.
Unlock ignition unit retainer and fold down (wire clip)
remove ignition unit and xenon bulb together as a unit from headlight.
Install new bulb on ignition unit etc...

If you can find correct bulb from aftermarket supplier with decent QC..should be fine...look for EU based suppliers first...seem to have better specs and quality there than in China etc....but if you're risking $50 vs $100's for BMW parts...might be worth a gamble!...depending on how much trouble you think it is to remove wheel, well liner etc to get the job done?....

^^^ Pretty good instructions, so just let me reiterate the safety aspect - the part about removing all power to the Xenon ignition unit:

Quote:
Warning!
Version with xenon headlights: Danger to life due to high
voltage! Therefore, before removing, disconnect all
components from the power supply (lighting system and
ignition off).

Thank you both, the instructions are really helpful! I decided to go with brand name bulbs to avoid hassle in the future.

I replaced the bulb and it's possible to do it without removing the wheel (as some online guides suggest). It takes some effort and patience doing it the first time (it took me nearly 3 hours). I got stuck trying to remove the back headlamp cover and again unlocking the wire clip from the bulb itself. This car is built like a tank
