how to replace right rear abs speed sensor
 

Hi all,
My 2003 A6 4.2 has a code saying that the right rear abs speed sensor has a fault to short. I bought a new sensor on ebay and am now trying to install it. I can not figure out how to access where the sensor is plugged in. It seems to be up in the frame of the car. Can someone who has done this replacement before give me a clue on how to di it? Thanks

My Bentley says you have to remove the rear seat bench out of locking mechanism.
Apparently the connector is under the seat.
Then you push the grommet/cable through the panel.
The sensor has a retainer on it that you remove and then pry the sensor out of the wheel housing.
You use brake wheel cylinder piston lube (a grease that is compatible with brake fluid!) to lube the sensor and push it in and lock it in with the retainer.

thanks! What does the Bentley say on removing rear seat? I have a vag but I really need to get the bentley!

pull up on front of bottom seat cushion
 

On my 2002 4.2, I just pull up on front of bottom seat cushion. There are 2 u-shaped springs that lock seat cushion into place (no screws or nuts). You can't see them as they fit into a slot in body that is hidden under seat. Rear part of cushion slides under seat backs.
