First, check for any warning lights on the dashboard and note down the codes. Then, perform a diagnostic scan using an OBD scanner to get more detailed error codes. Based on the codes, you can narrow down the possible issues and proceed to check the spark plugs, ignition coils, and fuel injectors for any damage or wear and tear.

If the car is not accelerating properly, it could be due to a clogged air filter. You can easily replace it yourself, and it is recommended to do so every 10,000 miles. Additionally, check the oil levels and make sure it is not overfilled or underfilled. These simple checks can often solve engine performance issues.

Another common issue in BMW XMs is a faulty Mass Air Flow (MAF) sensor. This can cause the engine to run rough and decrease fuel efficiency. It is best to replace the sensor if it is faulty, rather than trying to clean it. Some aftermarket options may be more affordable than OEM.
