Why is my Audi 80 producing excessive exhaust smoke?

I noticed that my Audi 80 is producing more exhaust smoke than usual. It has also started to smell like fuel. What could be causing this issue and how can I fix it?

This could be caused by a number of issues, such as a clogged air filter, a malfunctioning turbocharger, or an oil leak. It is best to take your car to a mechanic for a thorough inspection and diagnosis.

Check your spark plugs and ignition system first. Worn or fouled spark plugs can sometimes cause excessive exhaust smoke. If they are dirty or damaged, replace them to see if that resolves the issue.
