I've noticed that my BMW 2 Series hatchback is making a strange knocking noise whenever I start it up and accelerate. It only happens when the engine is cold and it goes away after a few minutes of driving. Should I be concerned about this? What could be causing it?
ReplyIt is not uncommon for BMW engines to make a knocking noise when they are cold, especially when the temperature drops. This is typically caused by piston slapping, but it shouldn't cause any major issues.
However, if the knocking noise continues after the engine warms up, it could be a sign of a more serious issue. It's best to have a mechanic take a look and diagnose the problem to make sure everything is functioning properly.
Additionally, it's always a good idea to follow the recommended maintenance schedule for your vehicle. Regular oil changes and tune-ups can help prevent any potential engine issues.
