Parking sensors

[Rozza30]

Hi recently purchased Audi TT 2007 and my parking sensors don’t work no sound when reverse engaged no beeping when reversing any ideas

My advice would be to get a diagnostic check carried out or get an auto electrician take a look. It could be: 

Broken wiring for the sensors 

Failed sensor module 

Failed sensor speaker 

Broken sensor (but less likely as all aren't working) 

sensor in the gearbox/stick that failed... so it doesn't register the car going in reverse, hence no beep, no lights, no parking sensors... This I think is most likely.
