I've noticed that my BMW Z4 engine makes a rattling noise when I start the car or accelerate. It doesn't seem to affect performance, but I'm still concerned. What could be causing this and how can I fix it?
ReplyFirst, check the oil level and quality. Low or dirty oil can cause engine noise. If the oil is fine, it could be an issue with the timing chain or a faulty engine mount. It's best to bring your car to a certified mechanic for a proper diagnosis and repair.
