I've noticed that my Audi A4's engine has started making a weird knocking noise lately. It seems to be coming from under the hood and gets louder when I accelerate. What could be causing this and should I be concerned?
ReplyIt is possible that the knocking noise is coming from a malfunctioning spark plug. This could be caused by wear and tear or a faulty plug. It is important to have this checked by a mechanic to avoid any further damage to your engine. I recommend asking for a spark plug replacement to resolve the issue.
Another potential cause for the knocking noise could be a problem with the fuel injector. This could be due to a clogged or malfunctioning injector. I suggest getting a fuel system cleaning to see if that resolves the issue. If not, it may be necessary to replace the fuel injector.
In some cases, the knocking noise could be caused by low oil levels or poor quality oil. It is important to regularly check your oil levels and replace it with quality oil. If the issue persists, I recommend taking your Audi A4 to a certified mechanic for a closer inspection.
