When I first got my X5, the driver's side halo bulb went out and I got that error. I went to the parts counter at Otto's BMW in West Chester expecting to pay $10-20 for an overpriced bulb, but instead was told by the parts guy that the price was $50. I said no thanks and bought an error-free set from eBay for $60.
