Parking sensors help
 

If any one can help me that will be great

Some one ran up the back of me and popped out my parking sensor

So I took it out as the plastic part came off. So I fixed it all up and plugged it in
But not they come on and stay on then go off but the light what you can turn them on and off with is flashing.

If any one can help that will be great.

Sounds like its broken. Flashing PDc light and long beep is a dead sensor.

or a broken wire...

If it is a broken wire at the sensor plug then it can be repaired. The plugs for the sensors come apart, the pins come out, little soldering of wire back on, and all snap back together cleanly.
