PARKING SENSOR MALFUNCTION??

[Adensar]

Sometimes when using the PDC function on my 2001 X5 e53 i get a constant tone. if i switch it off then on again sometimes this clears.

This is intermittent and most of the time the front/rear sensors behave normally.

Is this a fault or just somthing i am missing??

It's probably one of two things when your in park a) you've parked too close to the car behind or you're too near too the car in front or b) sometimes this happens to mine and it's just dirt on the rear sensors so give them a wipe with cloth and it should be fine. But to confirm it's not a fault because it does happen to me when I've parked up and I'm waiting there for someone outside a shop and I just turn it off to avoid the noise.

You also could have a bad sensor, it should be fairly easy to figure out which corner is constantly tripping when nothing is around I have a similar issue with my right front its just a bad sensor which I have not replaced yet.
