Hello everyone, I need some help so any suggestions would be appreciated....I have rear parking sensors on my 2002 audi a6 2.7t, 6 speed. For some reason now whenever I put the car in reverse there is this obnoxious loud beeeeeeeeeeeeeeeeeeeeep, that waulnt shut up as if im about to reverse into a wall and then it shuts off after about 10 seconds, and they do not work, i have tested them by almost hitting a wall behind me and they did not go off. Any suggestions?

 

I would stop by a junkyard a grab a few out of a toasted car and try replacing them.
