E65 7 Series parking sensors

[S70JPS]

I've had an intermittent PDC fail notice over the last few weeks. So today i decided to clean them, took the trim off removed the sensors. I assumed the colour coded cap was removable but managed to destroy the sensor. Question is how much do they cost and apart from a main dealer where can i get them from? Help advice much appreciated.

A faulty sensor can easily be heard if you activate the PDC and put your ear next to the sensor , the one making a clicking noise will need replacing.

I had three fail on my e38, IIRC dealer price was £120 each.

Needless to say, they were sourced elsewhere :-)
