My driver's side went out two months ago and the idrive alert came up. The SA said that it wasn't a bulb. Apparently angel eyes are made of fiberoptics and must be replaced as a whole unit. And they did, I was it would cost $1000 to replace if out of warranty. I would just take it in and let BMW worry about it.
