VW will sent it out FOC but there is ONLY one plaque per car so if it has been issued previously then they don't have another one to send out, no matter how much you offer them.
A member on here has (in the past) organised a Group Buy for peeps with any Mk5 to get a plaque for their car, all they needed was their plaque number or build number if a standard GTI....
