My driver side brake light went out. Strange that there was no warning on the dashboard about it. I had to take the X5 in for a periodic checkup and was told that the bulb had not burned out but burned something up! Worse yet, I was told that it was going to cost north of $250 because it wasn't part of the warranty.
Armed with my laptop computer (and BMW's wireless access) I did a couple searches on this website and found that this was called a "common problem" by many other drivers. Showing this to the manager helped them see things my way - they classified it as a "good will" warranty repair - and I saved some money!
Thanks to all of you here for helping out a fellow X5er in his hour of need!
.....time for me to go renew my x5world membership!
