2019 ibiza fr rear park sensors

[mstew20]

Just bought 2019 seat ibiza fr. It has rear park sensors installed in the rear bumper but no audible sound when reversing.

Having them fitted does this mean they are activated? Or is it something that can be activated by obd?

Car has no park sensor button next to gearstick or anything in settings section of stereo.

Thanks

They sound like aftermarket sensors

I am thinking that as well as i have been googling since I posted and they are not part of the bumper like the photos I have found and like my neighbours polo’s.
