Hello,

I have had my doors looms apart to do a B&O retrofit and it looks like the right rear is grey/green and right front was green/grey on my car (2010 4.2tdi RHD), the other side of the sensors go to brown which would be ground. they both seem to then go to the J393 convenience system control unit in the boot.

The sensors do fail and my car has had 2 already.

Good luck.

Great info, thanks! When they fail, do you have to replace and repaint the handle?

If you go to partsbase.org it looks like they are a separate part inside the handle, mine were changed under warranty so I'm not sure. You can get the handle out without taking the door apart using a Torx screwdriver, I.m sure there must be a video on the net somewhere for this.

Again very valuable input! There are a few vids on other cars and I deduced the D4 A8 would be similar and found the torx screw but also found out that the control unit could damage the sensor if faulty. As they've been changed once already at only 3000 miles I may need to change the control unit at the same time.
