i just had a look at mine, couldnt see any part numbers, but as someone else already said its the vvt solnoid, if u ask vw for a picture of the vvt compenents it should hopefully list it there, i hope for your benefit it is available seperatly as it looks expensive and possibly a bit of a slag to fit. It shouldnt really do any damage driving it, you will probably just get a lack of power.
