Hi Everyone, New Posting on here but im having a problem with my 2014 A6 S-line ultra rear parking sensors. They stopped working after i presume someone reversed into me in a car park and drove away as there was small mark on driver side rear bumper and rear parking sensors stopped working. Fault i am getting is: Supply voltage for park assist sensor Open circuit/short circuit to ground. I thought issue might be a damaged sensor from the impact it got, replaced sensor but issue is sill there. Checked fuse and this is good. All wiring on connectors to sensors look ok, no frayed or damaged wires. I get the long beep when put into reverse. Parking aid screen shows and x on rear parking sensors, front sensors are working ok. Cannot see any post on here already with similar issue. If anyone has experienced an issue like this any help is appreciated.
