Speaking of the rear lights only...You also want to inspect the bulb holder and the metal contacts near the base of the bulb as the bulb is fitted into the holder. If they don't make contact properly into the tail light assembly, you'll get no light and therefore an error message on the MID.

I found that cleaning the contact points with a little vinegar and water solution kicks ass, and bending the metal contacts in the bulb holder with needlenose pliers outwards solved my problems with alleged burnt out taillights on my 01 X5.

If you take a good look into the assembly, you'll see the way that the metal to metal contact is made. If the metal of the bulb holder does not reach far enough to contact the metal in the assembly as it twists into the assembly, you can manipulate the metal on the bulb holder with pliers. The assembly contacts are not malleable, they are fixed and solid. You may have to try several time to get contact made. Give it a shot. It might save you some $$.

Good luck.
