Why is my Audi A4 producing white smoke?

I recently noticed that my Audi A4 is producing white smoke from the exhaust. What could be causing this issue and how do I fix it?

White smoke coming from the exhaust can be a sign of a coolant leak. Check your coolant levels and inspect for any visible leaks. If the coolant levels are low, you may need to refill it and have the source of the leak repaired.

Dirty fuel injectors can also cause white smoke in your exhaust. Consider getting a fuel system cleaner and having your injectors professionally cleaned.

If your Audi A4 has a turbocharger, white smoke could indicate an issue with the turbo. Consider getting the turbo inspected and possibly replaced if necessary.
