01 a8L backup sensors failing
 

until a couple of weeks ago, all my sensors were working great.

the last few days, my sensor beeps were almost like there was something that was stuck to the bumper on a sensor as it was very sparatic and constant as soon as I put the car in gear.

now, today, the rear sensors are not registering any nearby objects, thought the front ones work fine.

is there something that could be as simple as a disconnected wire that can fix this?
