I’ve had a very enjoyable 2-weeks with all sensors working, now one of the front sensors has failed, which stops the rears being effective, so I’ll now go straight to a full set replacement.... I’m determined to get everything working on this car!
Keith, if yours are like mine were, they need replacing all together, I tried just changing the non-clicking one, but it didn’t work, they were all clicking and still not working? Removing the bumper is such a pain, it really is worth changing them all. I bought these https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F173457820998 , it helps that my car is black so no painting was needed. Good luck!
