On Wednesday I picked up the parts I had ordered from the Audi stealership, and worked that night to install them and get my seat back together. The new lumbar support went in easily. The back was a bit more difficult. Then last night I did the actual seat swap. Plugged everything in and started testing.

Forward - check.
Backward - check.
Up front - check.
Down front - check.
Up rear - check.
Down rear - check.
Lean forward - check.
Lean back - check.

So there is 4 of the motors in the seat... all good so far! Now for the important thing.

Lumbar up - check.
Lumbar down - check.
Lumbar out - check.
Lumbar in - check.

Whew! Already I'm better than before. Just two more things to check. But to check these I'll have to start the car. Nervously I inserted my key, and started it. The airbag light did not come on! Woo Hoo! I was very nervous about that. Final thing to check was the heated seats, and they're working great as well.

So now I have a new used seat. It looks like it doesn't quite match, but I haven't gone over it with leather cleaner yet. I can definitely say that it is so much more comfortable for me! My back is happy! :D
