Common issues with the BMW Z4 engine

I've been experiencing some issues with my BMW Z4's engine lately. What are some common problems that could be causing this and how can I fix them?

One possible issue could be with the spark plugs and ignition coils. Over time, these components can wear out and cause engine misfires. It's important to get them checked regularly and replace them if needed.

Another common problem is a dirty air filter. This can restrict airflow to the engine and affect its performance. Make sure to replace it every 15,000 miles or as recommended by the manufacturer.

Low or old engine oil can also cause problems and damage the engine. Check the oil level regularly and change it according to the recommended schedule to avoid any issues.
