A couple of A4 front grill questions

[A4B6Cab]

Thanks to a indecisive badger, I now have to make some repairs, so a few questions guys

the lower middle grill, will one from a saloon or avant fit on my 2003 convertible?

what are the 2 x metal things fitted to my (now smashed in half) lower grill, with wires to them?

Gents
Any idea what these are? They were mounted horizontally to my lower grille, have just cable tied them veretically to the bumper to keep them out the way a bit.. Any ideas?? Dont think they're parking sensors, are they aftermarket add-ons? I want to do away with them if I can

radar jammer?

A freind at work sugested the same, Ive had the car for 8 years and never had a warning (or known that I've jammed a radar), can i just cut them off and seal the ends do you think?

Trace the wire and see if it can be cut from the source, just incase it could lead to or be stopping an issue.
