S Line bumper vs Normal bumper

Hi guys,

First post on here so be gentle....

I bought a second hand A4 Avant S-Line earlier this year and I can say hands down its possibly the best car I've owned (also my first Audi).

Last week I parked nose in to a kerb, and when I reversed out the bumper snagged on the kerb and its effectively ripped the bumper! All the clips have held but it's peeled the bumper in half.

Now my question is;

The grille, fog lights, towing eye blanks etc are all sound.... But what is the difference between a normal A4 B7 bumper and an S-Line bumper, as they look all identical (difference of the grille etc, but I can replace that), as Audi and ECP claim there's a huge difference, but all I can see is the grille!!

Any advice, hints and mild abuse welcome.

Regards,

Dom
