What is this??

[Majni]

I just bought a 2007 Audi A3 8P and found this. https://postimg.cc/WhQ48DfF. Any clue as to what it is? Also, any way to fix the plastic around it? Seems like the paint is peeling off?

It looks like a button. What happens when you press it?

I think its an immobiliser of some description.  I used to have one in a car that i had to touch with a keyring before the car would start

neil is right,its an immobiliser and if its still wired the car wont start until you put a little fob up to it.i had the same thing in an xr4i.

Definately looks like an immobiliser, very similar to one my wife had on her old Fiesta

I got a little red fob (I just assumed it was an RFID tag for some other door or something so I took it off the keychain) with it but when I press it against it nothing happens, car starts perfectly without it. Is it original or did someone add it?

 

Edit: there's also capsule thing in a key that won't let the car start without the capsule being near the ignition. Is that it or?
