Why does my Audi 80 churn out black smoke?

I've recently noticed that my Audi 80 is producing an excessive amount of black smoke from the exhaust. The car has been regularly maintained and the oil and filters were changed not too long ago. What could be causing this issue?

It could be an issue with your fuel system or air filter. Make sure to get those checked and cleaned regularly.

Your car's engine may be burning too much fuel, causing the black smoke. Have a mechanic run a diagnostic test to pinpoint the problem.

Check your vehicle's spark plugs and ignition system. A dirty or malfunctioning spark plug can also result in black smoke emissions.
