WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The oil condition sensor is attached to the oil sump and is accessible from below. On all new engine types, there is no longer a dipstick. These engines have an electronic oil level check.
