Unfortunately - no way to know here. You'll have to consult your local BMW dealership service management to make a case for your concern and see if they can apply for assistance on your behalf. Keep in mind: This is where relationship is everything. If you are a loyal service customer for BMW and the dealership, they will be far more motivated to work on your behalf to get BMW to help, and BMW likely will want to know how loyal a service client you are before considering anything. Just real world food for thought. Good luck.
