What to check when my Audi 80's engine makes strange noises?

I have been noticing some strange noises coming from the engine of my Audi 80 lately. What could be causing this and how can I fix it?

The most common cause of strange noises from the engine is a lack of proper lubrication. Check your engine oil level and add more if necessary. Also, make sure to use the recommended oil type for your Audi 80.

Another possible cause could be worn out engine mounts. These are rubber parts that hold the engine in place and can wear out over time. Get them checked and replaced if needed.
