Welcome to the forum.
That is the identical car to mine. Silver with a black interior, 3.0I engine and the Sport Package.

If you don't have one in the family (can't see why not with all the BMW owners in your family) get a scanner that is made for the BMW. I have made several repairs to my BMW base on the ability to read the trouble code and saved hundred of dollars by not bringing it to the dealer or an indy.

I use BMW Scanner 1.4 when I'm at home, but I keep a bluetooth scanner in the car that works with an App called Torque on my cellphone.

I was able to repair my X while out Christmas shopping last year when it suddenly developed a misfire. Connected the scanner to the truck and it told me that cylinder No.2 had a misfire. Swapped the coil pack with cylinder No.1 and the new error code came back that cylinder No.1 was misfiring. Call a local auto part store near where I had the X and asked them if they had a coil pack for a BMW. Was surprise that they carried the coil pack and less then 30 minutes later the X was fixed and I was able to drive the family home.
