A new generation of rear parking assistance sensors has been introduced for XC90 model year 2007. Testing has shown that there can be false
warning/detection in wet conditions. This new sensor is painted together with a silicon ring, water can penetrate between the silicon ring and the sensor
which cause a constant warning due to hydraulic damping of the sensor.
Yes, since 2006w35 there are no painted sensors in production.
Yes please, if there are any false warnings after the service solution has been implemented, please contact your local help desk.
For vehicles produced before structure week 2006w35 change all 4 sensors to a non painted version P/N 30786968, use caution when assembling the
new sensors so that the ring is not damaged and apply silicon around the sensor according to the attachment "TJ 13977 instruction.pdf"
