2007 S8 tranmission not shifting in Drive or Sport mode
I haven't had a chance to pull codes yet, but plan to do so this evening. In the mean time, does this sound familiar to anyone? I called my preferred Audi shop, but they've never heard of anything like this and haven't worked on too many D3s (yet).
I have the same car. It dose sound like a switch between the D and the manual enable. I will look at the parts on the trany tomorrow and see what makes the distiction. I am out of town returning tomorrow can't wait to drive my car again and I will see if I can come up with something more usefull.

I believe that the brake switch was the culprit of a particular issue I had with my 2004 A8L 4.2. Similar to one of the OP's issues, I experienced it not shifting out of 1st when taking off from a stand still and when I did get up to speed (mostly on the freeway before I took it in) it would seem like the engine was loosing power but I believe what was happening was the transmission was going into neutral because it was getting a signal that the brake pedal was being depressed. Shifting from Drive to Neutral and then back helped get it going again for a bit. The problem was completely resolved when the brake pedal switch/sensor was replaced (I hope I'm not getting components mixed up...)

This also sounds related to another problem that occurred the same day the shifting issue started. I had someone following on the highway and they noticed my brake lights flashing when I was attempting to set the adaptive cruise control. I wrote it off as being too close to the guy in front of me, but at the time I was convinced I was back far enough. Perhaps this was the sensor going bad.
Now I'm starting to wonder if the 4-wheel alignment done earlier in the week is related too -- I had some sort of 4-wheel "super" alignment (apparently required when you have adaptive cruise control). "Super", in that it cost $390 at the stealership -- <i>thanks for picking that up, CarMax</i>.
Thanks for the info. I'll take it to the tech to hopefully expedite my recovery.

One final note is that on the way to the shop, the ESP faulted. Shop says this may be another symptom of the brake switch failure. This problem has not resurfaced since I got the car back, so perhaps it was related. I am still a little suspicious that this all may be alignment related.
