Are you sure you didn't just overfill it? The Passat has a drain hole at the top of the filler neck than dumps any overflow on the floor... could it be similar?
I would tend to agree, I think most (all) cars will have an overflow in case of overfill / expansion in hot weather and it may be that if you filled into the filler pipe the excess has run out.
