The check engine light means that there is a fault recorded in your
car's computer.  You should take it to your dealer and them do a
dump using their VAG 1551/1552 scan tool.  That will determine the
nature of the fault.  If it's just gas quality problem or something
and it has since gone away, then the dealer can just reset the computer
and make the check engine light go off.
