I recently unloaded my 05 X5 4.4. Tired of all the problems. Anyways, I bought a BMW charging system that you plug into the lighter. I only used once. Great for main taining full charge without over charging. Anyways, no longer a need for it;selling for $50 OBO plus shipping. Email me at
[email protected] if interested. This is officially my last post.Farewell X5 owners!
