I have a 21 m340. I always let it warm up first and get to operating temperature but the car stays in sport plus constantly. Is it gonna cause any excess wear and tear? Still have 1 year of warranty left on it.

    It’s fine. They wouldn’t have made the option if it caused excessive wear in the trans or engine. I think it simply changes the steering ratio and transmission shift speed and shift points.
