What are the symptoms and causes of BMW misfiring?
1 Answers
BMW misfiring symptoms include dashboard warning lights illuminating, difficulty starting, and unstable idling. The causes of BMW misfiring are as follows: Dashboard warning lights illuminating: When certain engine systems malfunction, the warning lights on the dashboard will illuminate, reminding you to check the vehicle as soon as possible. Solution: Check the vehicle's trip log. Difficulty starting: When this occurs, first consider environmental factors. If the weather is cold, it may be due to thick engine oil or significant battery power consumption. Otherwise, fuel pump supply or ignition system issues should be considered. Solution: Replace the ignition system. Unstable idling: This can be caused by a stuck idle motor, dirty throttle body, or carbon buildup inside the engine. If the air filter hasn't been replaced for a long time, leading to poor air intake, unstable idling may also occur. Solution: Regularly clean the engine internals.
