I recently purchased a used Audi A4 and noticed that when I start the engine, there is a loud noise coming from under the hood. What could be causing this and how can I fix it?
ReplyThis could be caused by a number of things such as a faulty belt or a problem with the exhaust system. It's best to take your car to a trusted mechanic for a thorough inspection to pinpoint the exact issue.
It's possible that your Audi A4's engine is just getting old and needs some maintenance. Try changing the oil, air filter, and spark plugs to see if that helps with the noise.
I had a similar issue with my A4 and it turned out to be a loose fan belt. Check under the hood and make sure all belts are properly tightened.
