Why is my Audi A6's engine making loud knocking noises?

I recently purchased a used Audi A6 and I noticed that the engine has been making these loud knocking noises when I accelerate. It seems to be getting louder over time. What could be causing this and how can I fix it?

Hello Sophia, loud knocking noises in the engine can be a sign of a serious issue. It could be due to engine oil not being the correct viscosity or low oil pressure. I would recommend taking your car to a trusted mechanic to get it checked out as soon as possible.

Hi Sophia, another possible cause of loud knocking in the engine could be worn out engine bearings. This is a common issue in older cars and can be fixed by replacing the bearings. It's important to get this checked out and fixed to prevent further damage to the engine.

Hey Sophia, it's also possible that the knocking noise is coming from a loose or damaged component in the engine. This can include the timing chain or accessory belt. Get a mechanic to inspect the engine and replace any damaged parts to fix the issue.
