Yes, undoubtedly. I'm not suggesting that BMW does not have internal quality control over the components that go into their vehicles. They qualify external vendors who supply them with those components. That being said, those vendors are also capable of supplying the same quality components/fluids to other retailers (or selling them directly). Obviously there is a vast range of quality when it comes to aftermarket or OEM parts. The discriminating consumer knows the difference or eventually learns the difference. But to suggest that buying OE "BMW" components from the dealer is the only way to get quality materials would be misleading.
