The old A3 has developed a internal sqeak whenever i hit a slight bump. Its a bit like them sqeaky toys that used to make the sqeak as you bounced them up and down on the string. It sounds behind me and then other times just to my side. Cannot track it down and even though not loud its bloody annoying on a 4 month old motor. Dont wanna get Audi involved just yet. Any thoughts apart from a mad mouse taking the piss.
