The recommended tire pressure for the BMW Z4 3.0i Roadster is 32 psi for the front tires and 35 psi for the rear tires. Always check the tire placard on the driver's door jamb for the most accurate information.
First, check the fuses related to the convertible top. Ensure the trunk partition is properly positioned as the top won't operate if it's not correctly in place. Also, check for any hydraulic fluid leaks or electrical issues.
Common maintenance tasks include regular oil changes, checking and replacing air filters, inspecting brake pads and rotors, checking coolant levels, and regular tire rotations.
To replace the cabin air filter, locate the filter housing under the hood near the windshield on the passenger side. Remove the cover and replace the old filter with a new one, ensuring the airflow direction matches the arrows on the filter.
Rough idling can be caused by dirty or faulty fuel injectors, a clogged air filter, vacuum leaks, or issues with the spark plugs. Perform a diagnostic check to pinpoint the exact cause.
Check the battery condition and connections, ensure the fuel pump is functioning, and inspect the starter motor and ignition switch. Faulty key fob batteries might also prevent the car from starting.
It is generally recommended to change the transmission fluid every 60,000 to 100,000 miles. However, refer to your vehicle's manual for specific intervals and use fluids that meet BMW specifications.
Signs of a failing water pump include coolant leaks, overheating, a whining noise from the engine area, and steam coming from the radiator. If you notice these symptoms, have your water pump inspected immediately.
