Hi, I just bought my first new BMW this week and the dealership made me sign a waiver stating that any aftermarket parts can void the warranty somehow, which I didnt have to do for the car I bought last year for another brand. Ive read online that there is a Magnusson Act (?) that somehow protects the warranty, in that the dealership must be able to prove that the defective part is linked to the aftermarket part somehow. My question is, will a seemingly cosmetic mod like installing aftermarket aluminum pedals (the ones you just drill on top of the current ones), affect the warranty in anyway? I'm leaning towards no, but then I'm thinking perhaps by adding aftermarket parts to the pedals, it would change the weight of the pedals, etc, and the dealership can somehow connect that to the brakes or clutch wearing down faster because you push down harder than normal. Any thoughts or personal experiences?
