Audi_RKT....(Bedros)

while driving yesterday I noticed the passenger side xenon is yellowish. The driver-side's xenon is still blue.

Anyone has similar problem. Should the dealer change one bulb, or change both pair.

Thanks.

They are fine. Replacing one or both can still give different colors...

I prefer the yellow, they came standard on the A8L and S6 models at least. Not sure about other models. Dealer cost is slightly more expensive on the yellow.

The bulbs change color drastically during the early part of use. So drive with your lights on for a couple days and check again.

That might or might not fix it.

I turned them on this morning and they were fine. However, lastnight after driving for half an hour, the passenger side turned into yellow.

I'm pretty sure it was yellow, and it's not my vision. If it's yellow again tonight, I'll take pictures.

There are two bulbs on each side -- the autoleveling HID bi-Xenon (behind the coke-bottle focusing lens) and a halogen bulb (in front of the multi-element reflector) to 'fill in' the foreground.

Get thee to a dealership for warrantee replacement!
