How to fix the engine oil leak in an Audi A4?

I recently noticed that my Audi A4 has been leaking engine oil. I checked the oil level and it seems to be decreasing. What could be causing the leak and how can I fix it?

It is possible that the oil leak is caused by a damaged oil seal or gasket. To fix this, you will need to replace the damaged part. I recommend taking your car to a mechanic for proper diagnosis and repair.

Another possible cause for the oil leak could be a worn out oil filter. Check the filter for any signs of damage or wear and replace it if necessary. Remember to always use high quality oil filters for your Audi A4.
