I just picked up new wiper blades for my 04 directly from Audi. 24 bucks each. They work well, they dont have the metal arms, so they look like the flex ones...i would suggest this route.

 

I just replaced my wipers at the Audi dealership after reading that you need Audi specific wipers and feel ripped off. They were $60 for the driver and passenger wipers!!!! No wiper is worth $30 each, even if made by Audi.

 

thats gay, they dont fit right, crappy tire says they do, but i say they dont,

 

Although that price does seem expensive compared to the $18 each that was mentioned earlier on the thread, I tend to disagree.
The Armour All single piece wipers from Canadian Tire work great on the other cars I've had and they cost about $25 each, well worth the cost.

Apparently they don't fit the Audi's though...
