I recently purchased a BMW 4 Series and I'm noticing some issues with the engine performance. The acceleration seems to be lacking and there is a delay in shifting gears. What could be causing this?
ReplyHi Laura, it sounds like your BMW 4 Series may have a faulty engine control module. This could be causing the lack of acceleration and shifting issues. You may want to take it to a BMW certified mechanic for further diagnosis and potential repairs.
Laura, have you checked the air filter or spark plugs? These are common causes for engine performance issues. Make sure they are clean and in good condition. If they are dirty or worn, replace them as soon as possible.
