On most vehicles the oil filter usually is in a position where when it is
removed no oil will drain except from the filter itself depending on its
mounting position.  As most VW filters mount vertical there usually is very
little spillage if carefully removed.  Of course this is assuming that the
engine is not running, or leaning at a severe angle (about 90 degrees)
towards the filter.
