How do I fix the fogging issue on the windshield of my Audi A2?

I recently purchased a used Audi A2 and have noticed that the windshield fogs up easily, even when the weather is not particularly humid. It significantly affects visibility while driving. Is there a specific issue with Audi A2 windshields and how can I fix it?

It is common for Audi A2 windshields to fog up due to a faulty seal. I recommend taking your car to a certified mechanic to have them check and reseal the windshield.

I had a similar issue with my Audi A2. After much research and trial and error, I found that using a specialized anti-fog windshield cleaner and regularly replacing the cabin air filter solved the problem.

Fogging can also be caused by a clogged drainage tube in the sunroof. If your car has a sunroof, be sure to have the drainage tube cleaned and maintained regularly to avoid fogging on the windshield.
