Why is my Audi 80's engine making a knocking noise?

I recently noticed a knocking noise coming from the engine of my Audi 80. It seems to happen when the engine is cold and goes away as it warms up. What could be causing this and how can I fix it?

This could be caused by a variety of issues such as worn out engine bearings or loose valve lifters. It is best to take your Audi to a trusted mechanic for a thorough diagnosis and repair.

Make sure to also check your oil levels and change the oil regularly. Low oil levels or dirty oil can also cause engine knocking. And don't forget to use the recommended oil for your Audi 80.
