The 2011 BMW Z4 sDrive30i is a moderately easy car to maintain. The non-LED rear lights are easy to access in the trunk, allowing for reliable bulb changes when necessary. The brake fluid reservoir has very open access, so monitoring its fluid levels and refilling it shouldn’t be a problem. The battery has relatively open access in the trunk, making it easy to reach should it ever need to be replaced.
However, the 2011 BMW Z4 sDrive30i does have its downsides. The engine air filter is secured by multiple bolts and fasteners, and it may be a problem to remove given its bulky size. The petcock doesn’t have very reliable access, as you’ll need to remove a large panel from underneath the vehicle in order to access it. It is also inconvenient to check the oil level, as you’ll need to turn on the car to check it via the dashboard menu.
