replacing blutooth module in b7 rs4
 

so my blutooth wasn't working and I did some digging and figured out that the blutooth module under the passenger seat had at one time been swimming in a puddle of water from a leaky windshield replacement, so I bought a new (used) module, will I have to have it programmed at the dealer to make it work? or is it plug a play?

thanks!!

nobody?
