Yes.

It is actually covered with the 4yr/50k maintenance plan and not the warranty. Sorry to split hairs

Indeed, that is a more accurate statement.

Completely correct. And now to split hairs a bit further, brakes are included in the full maintenance plan, but not in the scheduled maintenance plan.

In the US, BMW includes full maintenance. In Canada (as an example) BMW includes only scheduled maintenance, ie no wear items such as brake pads and wiper blades. We can upgrade to full maintenance at time of purchase. In much of the rest of the world, maintenance plans are available at extra cost and not included in the vehicle sale price.
