[A4] head lights

[JeffR]

Well i purchased my Audi about a month ago.  It's a 2000 1.8T and about 
a week or so after i got it the left headlight went out (it was raining 
at the time). i went back to appleway Audi (the place were i got it in 
Spokane, WA) and they replaced the bulb (not sure if it was just because 
they were nice or because it came with a 2yr warranty).  I just took my 
first trip to Seattle with my new Audi and it was awesome...so smooth! 
(like i need to tell you guys how smooth Audi's are haha) anyways before 
i left i noticed there was some condensation on the left headlight.  i 
thought that was strange as the right headlight was clear.  The day i 
was coming back from Seattle in the morning i turned my car on to leave 
and it said a light was out.  i went out and saw that the right 
headlight was now out.  i was going to take it to Audi again on Monday 
but was curious if there could be some greater issue here or just 
coincidence.  Thanks for any ideas in advance!
