How to check for BWM engine failure?

I have noticed that my BWM engine is not running as smoothly as before. I am concerned that there may be an issue with the engine, how can I check for engine failure in my BWM?

First, perform a visual inspection of the engine for any signs of damage or leaks. Then, check the oil and coolant levels to ensure they are at the appropriate levels. Next, listen for any unusual sounds coming from the engine while it is running. Finally, consider bringing the car to a certified mechanic for a diagnostic test.
