2009 Audi A6 2.7tdi rear pdc sensor replacement

[shaz75]

Hi Folks, needing a bit of advice.

One of my rear parking sensors, 2nd in from rear passenger has went faulty. When I put the car in reverse it comes on with a long beep.

How hard is it to replace the sensor, I have read u need to remove the bumper to access and replace the sensor.

Also does anyone know the part number for this sensor. My car is a 2009 (C6) A6 2.7tdi s line.

Thanks in advance.

Do a search on the forum, there are a couple of guides and one where you don't need to remove the bumper. The part number has also been posted a few times too.
