Thanks! I plan to check for any obvious wire harness issues first, then double check fluid level @ 45c. And, possibly pull the TCM and clean (check) the sensors of any metal particles. If I find metal I'll reinstall and cross my fingers.
After receiving your rebuilt TCM did it have to be re-programed?

Im sorry to say this but its time for you to get rid of the car. I had mine and i had the same code, took it to the dealer and the only way to fixed was the rebuild tmc which i got quoted almost 2k for it. Changing the fluid its not going to help because i did that too and didn't change anything, transmission started slipping in reverse so i made a decision to get rid of the car and and not worry about it anymore.
this is my story with this code but good luck..

I thought Audi had gotten their act together since the 90's?
Sad.

I was quite surprised at how easy it is to R&R the TCM.
1) raise car so it sits on jackstands level and tires are about 8" off the ground.
2) drain fluid
3) unbolt crossmember / transmissiion mount - It will have to hang against the exhast.
4) disconnect TCM connection
5) disconnect cable support at top of transmission cover
6) remove 12 cover bolts, cover and old gasket
7) remove three bolts holding TCM to transmission and remove TCM
Install in reverse order.

Thanks,
I was concerned that some spring or?, would come flying out. But it doesn't sound too difficult. There is a fair amount of room under there since it is FWD. I do feel a bit more comfortable now but still think it's to soon for transmission problems. I've owned 16 German cars over the years and never had a transmission issue besides clutch parts. Most of my cars had 200,000 plus before selling them, and most were manual...
Thanks again. I will dive in this week or very soon.

I finished the TCM repair / re-install at a total cost of $875.00. XeModeX in Canada repaired my TCM and it took less than three days to complete the repair. I pulled the TCM and shipped it on day one, they received, repaired and shipped on day two, I recieved it on the morning of the third day and installed it that afternoon.
Filling the transmission wasn't an issue either. I used a gear fluid oil pump (Item #40714 harbour frieght) to fill it. The tube fits snugly into the filler hole and didn't allow any overflow.
A new gasket was $10.00 from the dealer and I'm cheap so I reused the original bolts without a problem.
It's running fine and no more flashing "PRNDS"

Yes you have to remove the rear cover to remove the TCM
I didn't use a temp gauge at all to fill the fluid. I got the car up to operating temperature (after filling the transmission w/ engine running) by driving around the neighborhood, and topped it off again. The fill port is a tube that goes about 3" into the transmission allowing you to fill the transmission and any excess will drain back out. When you top it off make sure, the engine is up to temp, engine is running and you put in more fluid than is needed. Pull the fill tube and once it stops draining you are full.

So if I do nothing at all, and I can live with the problems with driving the auto(which are intermittent) how long will it still drive and what damage can it cause?

My wife drove the car for two years before I fixed the CMU. 95% of the time it drove normally and the check engine light would go out occasionally. The delay was mostly financial because I was not going to pay over $2K to have the dealer fix it and couldn't find another source. Once I found the source, time was still an issue. There doesn't seam to be any type of internal damage and there was no metal in the fluid to speak of. If your only issue is the flashing indicator then I don't think it will cause any other damage to continue driving it.
