Parking sensor problem

[gingergoolies]

Hello everyone

Has been a long time since I posted. Hope everyone is keeping well!

My parking sensors have decided to play up........stick it in reverse and you get a long high pitch bleep (higher than usual) then it stops working.
If you take it out of reverse and select reverse again you get nothing at all.
They work sometimes but it's becoming more frequent that they aren't working. I'm not too bothered about them but my partner relies on them a lot.


Any known fixes/diagnosis?

Thanks
