Progress...
I finished the install, but I have yet to do the coding. Here are some pictures and comments/thoughts for those of you with
MMI Low.
Helpful tools/Parts:
- 6 foot Network Cable - Cut of the ends, take three strands and you have the perfect wire. Do not separate the intertwinded-ness of two wires.
- Friction Tape
- Torx T25
- 8mm ratchet bit
Passenger side comments
- Make a harness with the connector and three wires. I sent one wire to the driver's side and two to the passenger side. If you have ever worked with a computer network cable, you know that pairs of wires inside are twisted together. I did NOT undo the twisting for the two wires going to the passenger side.
- Running the wires to the passenger-side fuse box is not hard and does not require you to remove any major parts. Follow my wire-path in the following two pictures. First send the wire down the side of the center console. Then slide it into the crack in the paneling above the passenger's legs. use your fingers to move the wires out of the way of the A/C vent holes. This took about five minutes to complete.
- Once the wire is all the way to the end, you can easily feed it up to the fuse box. Pop open the fuse panel and just thread it through. Once it is there, untwist the pair of wires and attach one to the body for ground. The other can then be properly attached to the fuse box (but this requires you to remove panels). I chose to tap the CD fuse. Make sure you tap on the left side, not the right. Both will work, but using the left side will allow the fuse to be inline and provide some protection. MAKE SURE YOU PUT THE PROPER WIRES ON 5V and GROUND. MIXING THEM UP WOULD BE BAD.
Driver side comments.
- You will need to remove the panel above the driver's legs. You will need an 8mm bit to remove the 3 bolts.
- Run the wire similar to that done for the passenger side. In my picture, you will see two white wires. One is the new ADS wire, the other is the wire I added for Hill-Hold. Run the ADS wire up and over. I found an empty hole in my car that was a natural place to run the wire through. Be careful that your wire does not get in the way of any pedals. Double check this when you are done.
- There is a black plastic fuse frame/box in the way. Remove the black screw shown in the middle of the picture. It requires a T25 torx bit, but it is only hand-tight. Press a plastic lever on the left and the frame is free to swivel down. Note that the right side is attached in the form of a plastic hinge. Remove the frame and it will be easier to get to the tan connector we need to tap.
- There are two tan connectors behind the box. We need the one in the left that looks like it has a hood and a release tab on the hood's right side.
- Attaching the wire is actually, not too bad. First you unplug the tan connector. Once you have the connector in hand, you will realize it is a black plug (that looks like a small floppy-drive connector from inside a PC) covered with a tan shroud. Remove the shroud. Once there, we need to add the wire. I simply stripped 1cm off my wire and slid it into the tiny hole that the lavender wire (pin 4) is in. Then I used friction tape to tape my new wire to the existing wire bunch and keep it in place. I did not do any splicing. My wire is not perfectly secure, but since it is completely out of the way and taped into place, I am not too worried about it coming lose. Sadly, I did not think to take pictures until after I put this all back together.
At this point, I have the switch and wires all in place. I notice that the switch does not look like it has power or looks functional in any way. I am pretty sure that it will show life once I do the VAG-COM work. I will let you know.
Hope this helps someone....
******************* EDIT *******************
I made the VAG-COM changes and it seems to work. It lights up and I can definitely tell the engine responsiveness changes, not so sure on the steering stiffness. I will keep playing. I did the following:

I did not do any adaptation changes because I like the auto to be "stock".
