Original BMW PDC Parking Sensor Decoupling Ring - BMW 5 Series, 6 Series, 7 Series, X3, X5, and X6 (2004–2019)

BMW uses this small decoupling ring to seal each Park Distance Control (PDC) sensor on a wide range of 5 Series, 6 Series, 7 Series, X3, X5, and X6 models built from 2004 to 2019. BMW calls it "decoupling ring PDC." It weighs about 1 gram and is sold individually. The ring keeps dirt, debris, and moisture away from the sensor's electrical components. This Original BMW piece is made in Malaysia. BMW shows production of the current number starting in September 2007.

Original BMW Parts carry a 24-month parts warranty.

A PDC sensor reads distance by sending and receiving ultrasonic pulses. The ring around it forms an airtight seal that keeps dirt, debris, and moisture away from the sensor. Number 66-20-9-142-107 replaced the older 66-20-6-986-297, and BMW marks the two as exchangeable retrospectively. That means the newer ring also suits earlier cars that were built with the old number. The rings are priced and sold one at a time, so count the sensors you are servicing and order that many.
