On mine it was the "linkage connecting rod" that had broken. I was able to avoid the expensive part replacement with getting "2 x 10mm Ball & Socket Joint M6 Right Hand Thread Linkage" and some "M6 threaded rod" and made up a new linkage. I later found someone selling a made up kit on an internet auction site. After market sensors are also available to avoid dealer prices.
