I recently purchased a used BMW 3 Series and noticed that it has a rough idle for the first few minutes after I start the engine. Is this normal or should I be concerned? What can I do to fix this issue?
ReplyIt is not uncommon for older BMW 3 Series models to have a rough idle after start-up. This could be due to a dirty or faulty idle air control valve. I recommend having it cleaned or replaced by a mechanic to improve your car's idle.
Another possible cause of rough idle in your BMW 3 Series could be a clogged air filter. Make sure to check and replace your air filter regularly to ensure proper air flow and improve engine performance.
