Hi I’ve just fitted a new grill but had the ugly foam behind it has anyone done the same if so did you keep the foam ? Or can it be removed ? Thanks 

If you have the plastic tube in the back of the foam then it must be kept as it’s for the active bonnet. The foam is also there to protect pedestrians from the crash bar as part of the active bonnet system. Some older Audi’s had a thin textured plastic cover that covered the foam behind the grille so this might be a good option 

This is a example of what I mean
