  7. Was finally able to record the mysterious sound I've been hearing!

    Volkswagen Passat B5 Discussion
    I have no idea what this is. I'm recording it from unde the steering wheel to the left near the gas/trunk release switches. It's almost like it's coming from the steering wheel itself. Or maybe from the wheels? The right side is starting to do it too I think? But perhaps it's the glove box. But...

  16. Mysterious Smell [2003 W8 Passat]

    Volkswagen Passat B5 Discussion

Unlike most smells, this smell is only present when the car is in motion, and more specifically, when the windows are rolled down. My theory...
