Mods, please add this to the correct sticky if you see fit. I finally broke down and bought the WIS softare in order to get the proper way to replace my actuator.
First, remove the door panel. (write up on that is already on this site).
Next you need to remove the door handle. First you need to pull the door seal out right around the door latch and there is a hidden allen screw behind it. It is 4mm (WIS software said 3mm, but mine was 4mm). Unscrew this screw 5 complete turns. Do not unscrew it all the way out as it will fall into the door and you'll need to fish it out.
Yellow arrow shows the allen screw. White arrow shows the door latch for reference:
Once you loosen this screw you can remove the door handle. From the outside of the door, pry the piece towards the back of the car (the part of the outer handle that does not move - yellow arrow).
Be careful not to scratch your paint. This part took me a long time and I tried from both inside the door and outside. Eventually I just hit it right and it fell out. Once this piece is out you simple slide the rest of the handle towards the rear of the car and it will come right out (the white arrow). Remove the rubber seals as well. This is what you will have at this point.
Now you need to remove the part of the door handle that is inside the door. In the last pic above, just loosen the 3 screws (dont take them all the way out) and then you can move the assembly towards the front of the car and remove it from the inside of the door.
Now it's time to finally remove the door latch/actuator assembly. Below is a pic of the latch/actuator assembly in the door. Remove all of the torx screws at the red arrows. Remove the air line at the yellow arrow (carefully!!! you dont want to break the plastic piece that holds this on...work it off carefully). The green arrow shows the lock rod that needs to be pulled out of the assembly as well. I did leave the rod on the door, I just popped it out at the green arrow. Once you have these all out, you can now work the entire assembly out of the door. (note: the very lowest red arrow in the pic you do not need to remove until you get the assembly out of the door....I removed it and it would be easier to remove it once the assembly is out).
Below is a pic of the assembly removed from the door. Pop the top of the actuator out of the metal piece (yellow arrow)...I just used needle nose pliers and broke the plastic, and remove the screw from the bottom of it (red arrow). You can slide the actuator out.
Now....to re-install in the opposite order!
Hope this helps.
