Any way to disconnect the front PDC and still have the rears?
 

Turns out I have not 1 but 2 front PDC sensors that are dead- both outer ones. I don't have time to pull the bumper to get at the sensors right now, too could outside and the race car is in pieces taking up the garage. Dealer said $500 parts and labor for the job which is nuts.

At the moment I've got the fuse pulled, but would like to at least have the rear sensors operating until I can get time to pull the bumper off. Has anyone figured out if the front circuit can be disabled?

Don't think so, I have a blown on in the front that I disconnected and the system still wont operate correctly..

Why pay $500 for parts and labor?
do a part number search on Google and compate prices the cheapest I found them was for $124 each. but that was a while back.

It cannot be done due to the failsafe system. Either you have all 4+4 sensor in good standing, or no PDC.

I think I saw a thread last week where someone pulled a PDC sensor meant for a Land Rover for like $35 and it worked flawlessly.

Good luck!

I don't want to spend $500. But at the moment, I've got a race car to put back together with the track season just 5 weeks away. So the X5 is outside in the driveway, and it's been too cold/ rainy/ snowy to pull the bumper myself. And work travel pretty much eliminates doing it during the week. Guess I'll have to live with the inop system for another month or so, until I can get to pulling the bumper.
