I just did this mod on the new car so I thought I'd try and contribute to the forum (just for the coupe guys at the moment).

This mod is to enable the one touch close feature of the rear vents in the coupe. Sedan guys have it easy and already have this enabled.

Tools:
PA Soft or some other coding method
Phillips
Small flat head
Dremel or something that can be used similar to a dremel

First we'll need to remove the shift knob and boot from the shifter (just pull up) - similar for the AT. For the knob put in neutral (both AT and MT) and pull like you've never pulled before...and don't smack yourself in the face.

Next we'll use the Phillips to remove two screws near the unlock button (ignore my dirty car):

Lift the trim piece up and unclip two connectors for the window switches. AT will need to remove a couple more connectors for shift lights etc.

You should now have a trim piece with two switch assemblies attached to it (four buttons). Remove the switches from the trim piece and get out the flat head.

Next use a small flat head to pry the inner switch out of the outer housing.

Once the inner switch piece is out you're almost done with the physical mod. The switch operates with a little plastic piece sliding back and forth on top of the inner portion depending on how the button is pulled or pushed. You'll noticed that you can push/pull on the sled to create tension and then a click. The click is the one touch feature. The rear button for the rear vent is limited by the outer housing you just removed the inner switch assembly from.

The following pictures shows the lip that limits the rear switch from fully engaging. If you think of the lip as the lip of your mouth you'll need to cut the portion where you're gum meets your upper lip. Right where the horizontal and vertical meet you need to cut out a groove so the sled can move the full distance.

I used a dremel like tool to achieve this. I'm sure you can get creative and figure something out. Once completed replace the switch back into the assembly to test that the buttons operates as you desire. To put the inner switch back in the outer housing you'll need to get the buttons lined up as if they were neutral between up/down then slide the switch back in the housing and click into place. You'll then be able to test if you took enough of the lip off to allow the one touch feature.

If you got this far then have a beer and start to code your car...ok hold off on the beer because you're about to code your car. You'll need a program or a friend who knows what they are doing.

I used PA soft and will briefly go over that here, but there are countless other places to learn how to use PA soft.

Launch PA soft and turn the key to position 2. Scan on PA soft.

After you've scanned the car double click the ZKE area to open that coding portion of PA soft.

You'll select "Coding Data" on the left hand side and then the following screen will pop up.

From there select "Recoding". On the left hand side of the new screen you'll see the "One Touch Feature" section. Select the box for "close rear window". Then select "Write" on the lower right hand side to code the car.

Grab a beer and enjoy the one touch close feature!

Thanks guys. I couldn't find any pics of what actually needed to be modded so thought I'd create this - with some nudging from Charlie lol.

Overall the hardest part was getting the switch out of the housing without breaking the tabs. Simple if you are delicate and take your time, but I can see how they would be easily broken by a buff dude trying to get his mod on.

Nice DIY Sean!

Bump. I think someone was asking about this.

Hey guys I just finished this 10 minute mod and used a suggestion from this e46f thread (https://forum.e46fanatics.com/showthread.php?t=1004064) to make it simpler:

Instead of grinding down the internal stopper lip on the frame, just trim the slider piece that hits it. Takes 2 secs with some end cutters/toenail clippers/whatev.
