I recently bought a used Audi A3 and noticed that whenever I accelerate, there is a knocking sound coming from the engine. What could be causing this and how can I fix it?
ReplyThe knocking sound you are hearing could be caused by a number of issues, such as worn out engine components or a faulty fuel injector. To properly diagnose and fix the issue, it is best to bring your car to a certified mechanic.
If the knocking sound only occurs during acceleration, it is likely an issue with the engine valves or spark plugs. You can try cleaning or replacing these components yourself, but it is recommended to seek professional help for proper diagnosis and repair.
