I recently noticed that my BMW 7 Series has a loud noise when I start the engine. It only lasts for a few seconds and then disappears. What could be causing this and should I be concerned?
ReplyIt is common for BMW engines to make noise during startup, especially if the car has been sitting for a while. This is usually due to lack of lubrication. However, if the noise persists or gets louder, it could be a sign of a more serious issue such as a faulty crankshaft or timing chain.
