Thanks so much for the response...I am DESPERATE to get this fixed...it is FREAKING me out because I am afraid I may do some damage...because I am fearful it will overheat...I have lloked at the expansion tank and cannot detect a leak or crack...unless it is ridiculously minute...I will do some more searching about the expansion tank upon your advice...I have to say I LOVE this car...It drives as well as everyone said it would...I have found the advice of members to be extremely helpful in the past with our E39 and our E36...

Since I am a newbie, I am not sure what you mean by "wafers"...I have lights that are far brighter than my E39 lights and are bluish white in color, but I like the face lifted look on the 2004's and sort of wish I had those...That would be an awesome mod...but first I need to get the coolant light out...it will make me crazy...

How many posts until I can post photos of my new to me x5?

Thanks for the advice I will keep reading!!!
