Sorry to hear that some BMW dealers are excluding vehicles from the BMW Value Services even though the website lists your vehicle as eligible. I was lucky that my local dealership honored the value service pricing that was listed on the website. They even brought it up before I even asked…when I took my f15 in for a brake service check.
If you live in an area that has multiple BMW dealerships…try the others to see if they will honor the service. Or try a zip code near you where another BMW dealership is within driving distance and perhaps make it a “day” of service…drive there to get the work done.
