I have noticed that my BMW 1 Series has been making strange noises and the engine seems to be running rough. What could be causing this issue and what steps can I take to diagnose and fix the problem?
ReplyFirst, check the oil levels and look for any visible leaks. Low oil levels or leaks could be the cause of the engine problems. If the oil levels are fine and there are no leaks, then it could be an issue with the spark plugs or fuel filter. It is always recommended to get a diagnostic test at a BMW dealership to properly identify the issue and get it fixed.
Another possible cause could be a faulty oxygen sensor. This can affect the performance of the engine and lead to rough running. If you notice a decrease in fuel efficiency or your check engine light is on, then it's best to get the oxygen sensor replaced.
