I have 2004 A4 Quattro. Last week i saw condensation in the passenger side head light. I checked the lights by switching them and both and the lights worked. Then i switched the ballast on the bottom of the light unit and the one on the passenger side had water in the bottom when i opened it, which i think it fried the ballast. I don't know why i am getting condensation in the light. I do live in ny where the weather is getting cooler but i had the car last year and had no problems. Being that it is cold out the condensation is not going away. I know i need a new ballast but i am afraid that if i put a new one in i will get the same results. Is there anyway i can stop the condensation
