    Mine does it too, i put it down to somehow being the cold as its never done it during the summer.

    Having said that, my mates fella's CD player indoors does it, as does the tape player in my other mates Punto so i've not got an explaination for it, but we arent alone lol.

    It's a design flaw with the earlier Audi head units. They use a memory chip to store every adjustment you make to volume/bass/treble etc in order that if the unit gets switched off it will retain the settings when you turn it back on even if the battery is disconnected. A bit OTT IMO but the huge meistake they made was making the memory non overwrite, so once the 10,000 locations are filled the whole HU becomes totally random and thus the volume with a mind of its own. And it will only get worse once it's started.
    The fix is quite involved - new memory chip, new firmware and new controller, so not really economically viable. Full explanation is here:
