Hi guys, I recently bought an Audi A4 Avant SE (B6) but the wiper noise is driving me crazy! So I took a look at the drivers side one first, lifting up the arm, but the wiper just kind of fell off into my hands - it doesn't appear to clip onto the arm? The pressure of the arm pushing it against the windscreen is the only thing keeping it on :S Here are some pictures: Wiper: Wiper Arm: The two arms: Can anyone tell if the wiper arm is broken or is the actual wiper broken? I'm CONFUSED! From what I've found on the forum, the B7 wiper arms & blades are better, but is it worth the upgrade from B6 Aeros? ANY help is much appreciated Thanks, Daniel.
