BMW X5 Parking Sensor Problem

[drex]

we've all done something similar on this board.

when i first got my 2nd X5, i took it apart and the whole neighborhood thought i'd gone mad....

welcome to the club!

Hello. I am looking for replacement sensors for a 2004 X5. I believe one of my sensors is broke (after I hit the side wall) and now my PDC is not working. After everything I have read, I do believe this sensor is bad. I would like to purchase one for the front side and one center sensor. Can anyone tell me where I can pruchase these. I live in Spain and going to the BMW dealer here and asking for one is like asking them for the first 5 children (impossible) Any help would be a great help.

Mine flashed and didnt work

but this happened after I waxed my car

I washed my car and it never happened again.

You approach the man and ask him if he's "OK?" he responds "Someone on the Internet told me to do it". I'll leave the rest to your imagination - needless to say my neighbour thinks I've thrown a cog.

Having said the above. . . You are spot on.. . ! - thank you for that gem of information. I have a clicking (4hz) from each sensor although some produce a "cleaner" 4Hz. I will this evening check all the electrical connections and re-listen. . I'll then replace the ones not producing a "clean" 4Hz.

Thank you once again all, I'll keep you informed (as long as my neighbour does not have me committed).


Cheers all.

As stated previously Samuel :xoutpost: and yes we have all done crazy things in front of our neighbours for these vehicles. If they are all clicking then the PDC computer has gone south.

Thank you Vitalik. I followed your method and it worked perfectly. To hear the ping better, I touched the metallic tip of the screwdriver to the parking sensor and got my ear closer to the handle. This seems to amplify the pinging sound of the sensor. It was loud and clear on all good sensors. The silent sensor just needed cleaning at the electrical connection. Cheers and thank you.

Yes, you can hear the clicking quite clearly to identify which sensor/s is/are not working.
