Parking aid

[Conor52]

Hoping someone can help.

Parking aid is not working when in reverse when I hit the button it beeps for like 5 seconds then cuts. Could it be sensors, module or loose wire somewhere.

Thanks

Welcome Connor. 
Most likely a sensor, but would need diagnostics to confirm, and if correct - indenting which one.
