You are Awesome, in fact everyone has been awesome with replies. Not my first Bimmer but it is my favorite thus far. The more I drive it the more I like it. I have the High version and it is not the Check Engine but the DSC Led they removed. It would have been lit when I picked it up if it had 1 as the were multiple error codes dealing with the transfer case actuator gear which I have replaced. I have fixed all the mechanical pieces on this X5 with the exception of the passenger side remote fold in mirror, it has some issues finding its position at present. Thank you very much for your post. I ordered a few of the LED's based on what Wayne had replied to me so it looks like I should be able to get my warning light fixed when they get her the end of next week. Shady used car dealers really Piss Me Off !
