I've noticed that my Audi A3's engine has been running rough lately. What could be the possible causes for this and what steps should I take to fix it?
ReplyOne possible cause for rough engine running could be a dirty air filter. It's important to regularly check and change your air filter to maintain proper air flow to the engine.
Another cause could be a faulty spark plug. If your spark plugs are worn out or dirty, it can lead to rough engine running. Consider replacing them to improve engine performance.
Low fuel pressure or a clogged fuel filter can also result in rough engine running. Make sure to have your fuel pressure and filter checked and replaced if needed.
