I have just managed to get my parking sensors working for the first time since owning the car.
Turns out there was a broken wire in the rear bumper.
The weird thing is, say i'm parallel parked between to cars. I put it into reverse go back to the car behind and the sensor beep as they should. if I pull forward the front sensor beep as they should. Now when pulling out the space and driving off after about 3 seconds the sensors start screaming until I either press the button or wait for them to turn off.
I have hooked my BT IID up to it but its not showing any errors.
Has anyone had this issue before?

I have had this intermittently but haven't found out what the issue is. It's strange and gives you a fright as if you're going to hit something. Current 2007 TDV8 Vogue Buckingham Blue

Does the noise happen if you can pull straight out of the space?

If not then it could be the adjacent car you are passing setting off the warning. Mine seems to give that. Cheers

No I can get past the car before it goes off.
I have ordered a second ecu to see if that helps.

I had this once. I just cleaned my sensors. seemed to sort it.

Si.
