Recognizing these symptoms early can help prevent further damage and ensure that the vehicle remains in good working condition.
Common Causes of Rough Idle
Several factors can contribute to a rough idle in the BMW 528i. Understanding these causes can help owners diagnose and address the issue effectively. Here are some of the most common culprits:
