Those holes in the grill are for AIR!!!!! to keep the engine and related parts cool. If you had a problem VW would probbly tell you you voided the warranty for putting the plate on the grill. I wouldnt risk it. how about velcrow tape on the bumber and on the plate??? The tape might leave some glue behind. But you could probbly get it off with some goo-be-gone and a little time.
