On a BMW Z4, the dipstick is typically located on the engine block, towards the front or side, depending on the specific engine model. In some newer models, however, BMW has eliminated the traditional dipstick and instead uses an electronic oil level sensor, which can be checked via the vehicle's onboard computer system. If you're unsure, consult your owner's manual for the exact location for your specific Z4 model and year.
On my 54 reg, its the middle of the steering wheel.
