Anyone know whether or not the supercharger is available from any other sources than the dealer? I just had the car to a german repair shop for a second opinion and they comfirmed that the supercharger is headed south and that they have never changed one before. Just my luck. I have done most of my own repairs over the years and am up to taking this one on. It seems like it should just be a bolt on part. Any one ever done one or know how doable they are???

Thanks!
