I recently noticed a knocking noise coming from my Audi A4's engine. It seems to be loudest when the car is idling. What could be causing this and how do I fix it?
ReplyIt's possible that the knocking noise is caused by a faulty timing belt or a loose engine mount. I would recommend bringing your car to a certified mechanic to diagnose and fix the issue.
Another potential cause could be low oil levels or dirty oil. Check your oil levels and if they're low, make sure to top it off with the recommended oil for your Audi A4. If the oil is dirty, consider getting an oil change.
