I bought a lower grill for my 2010 TC and I'm having difficulty gettting it to stay in place. The original was missing and I have replaced it so I can hang the front license plate. It fits fairly well but one side pops out, I don't want it to fall off or be easy to rip off the front.
The plastic flaps seem to slip out, they hold for a few minutes then slip. Drive to store and back its popped out a bit.
I'm thinking of using black silicone to help glue it in, the kind used to hold in the rear tail light covers on older cars.
Ive also thought about drilling a set screw in but this seems extreme and the front lower plastic is a bit flimsy.
update:
well. it stopped popping out on its own. I pushed back in one last time and it has stayed, so after a while the plastic conforms to the body. Would have deleted forum entry but I do not see a delete for a post.
