I have noticed that my Audi A2's engine makes a knocking noise whenever I start the car. What could be causing this and is it something I should be concerned about?
ReplyIt is possible that your engine could be experiencing issues with its internal combustion process, causing the knocking noise. It is recommended to have a mechanic inspect and diagnose the issue to prevent any further damage.
The knocking noise could also be due to low quality or incorrect oil in your engine. Make sure to use the recommended oil for your Audi A2 and have it regularly changed to prevent any engine damage.
Another potential cause could be a faulty spark plug or incorrect spark plug gap. I suggest having a mechanic check and replace the spark plugs if necessary to resolve the issue.
