I've noticed that my BMW 1 Series has been making a knocking noise when I accelerate. What could be causing this and how should I address it?
ReplyEngine knocking can be caused by a number of factors, such as low quality fuel, incorrect spark plug gaps, or faulty engine components. I suggest taking your car to a trusted mechanic to diagnose the problem and make necessary repairs.
One potential reason for engine knocking in a BMW 1 Series could be carbon buildup on the valves. I recommend using a fuel system cleaner to help remove any buildup and see if that solves the issue.
