    This was a new one on me...

    Presumably rain sensor = auto wipers? In which case I don't have it. My B7 is possibly the meanest spec in the country, it has no options what so ever! :)

    Self drying brakes? Thats a new one for me! Especially seeing as disc brakes are always dried by their rotation (and heat from being used!).

    I seem to recall very vaguely reading somewhere that the ABS system was capable of applying the brakes minutely - certainly not noticeable to the driver - to keep the pads and discs dry.

    What Jeff said. It pulses the brakes to keep them dry, great for discs, not so good on ECU's sadly...

    Why's it bad for the ECU?

    Regardless of ABS etc, don't the pads rub against the discs anyway?
