How to troubleshoot engine issues in a BWM vehicle?

I have been experiencing engine troubles with my BWM vehicle. It's been making strange noises and the performance has been significantly decreased. What could be causing this issue and how can I fix it?

First, check your engine oil levels and make sure they are at the recommended level. Low levels of oil can cause engine issues. If the oil levels are fine, then it could be a problem with the spark plugs or fuel injectors. I recommend taking your vehicle to a trusted mechanic for a diagnostic check.

Another common cause of engine troubles in BWM vehicles is a malfunctioning oxygen sensor. This can lead to incorrect air-fuel ratio and affect the engine performance. Get the sensor checked and replaced if needed.

Have you been using the recommended fuel for your BWM vehicle? Using lower grade fuel can cause issues with the engine. Stick to the recommended fuel and see if the performance improves.
