Fred: I saw your thread earlier and it makes me think I can fix it myself. But can you explain abit about how to read and rewrite the module code? I have vag-com cable but I'm very not familiar with it.
BudgetPhoenix: Does the transmission type matter? The one that I found on ebay is off a MT GTI and mine is a DSG...
Hum - not sure where to start. Using a VagCom isn't something that's very easy to describe in a simple post. Even worse, I still don't have one myself - just borrowed it from a friend to do my ABS job - and was lucky enough to have some last minute help from a mechanic buddy to assist with the four sensor adaptations that needed to be done at the end.
They include the Steering Angle ; Lateral Acceleration ; Brake Pressure ; and Longitudinal Acceleration sensors. There is also a System Function test which can be run. See Ross-Tech's wiki page:

Start by hooking up VagCom and doing an autoscan - which will result in a listing of all your available modules and their status. As I recall, the ABS system was module 04 - which you can then open and examine. Note the "long code" for the module (write it down very carefully) and also copy/paste it into a word file - make absolutely sure you don't accidentally change it and have several safe copies before proceeding.
I believe that long code is pretty unique to your car and suspect it's how the pump knows which options need to be activated - this is based on my assumption that the same pump is used in MT / DSG / and maybe even several Audi and/or 4 wheel drive applications (but could certainly be wrong about that - there may be several different pumps - suppose a Dealer parts guy could verify that for you). Also, you can compare the Part Number on your Ebay pump with the one in your car (although not sure how easy it is to read the label with pump still in the car). Make sure the used pump is well sealed (all ports closed off) to insure no dirt has gotten in it.
Once it's been installed in your car, you will eventually need to re-enter that long code into the new pump controller (using the same VagCom screen location).
You will also have to do the adaptations for the 4 sensors (at least that was the case for my car). I honestly don't remember the order in which the 4 sensors had to be set-up, but it seemed to be important to the ultimate successful completion. You will also need the "security code" for each one, which VagCom will provide - and must be entered to allow access to each sensor. When the adaptation is complete, your dash warning lights will go out, and the pump Long Code will be remembered.
Sorry about being vague here, but the adaptation was where I needed assistance and my mechanic buddy (who doesn't work on very many VW's) also was working in a somewhat "trial & error" mode, requiring several different attempts before we "got it right". I'm pretty sure I could do it again if necessary, but certainly not the first time, and not without a lot of cussing.
Assuming you get the pump installed and brake system properly bled - even if you fail to successfully complete all the VagCom programming / adaptations, you really won't be any worse off than you are now (assuming you carefully saved the original long code). Meaning - the car will be marginally driveable (with same problems you have now - no ABS / no Traction Control / Steering Assist problems, and all the crazy warning lights) so you could still search out a VW shop or even the Dealer to finish the programming work.
Perhaps start by finding a good local shop. That way you have a "back-up" plan if you can't complete all the VagCom coding. Just don't lose the "Long Code" from your original pump - have no idea how to re-create that if it gets lost.
Hope this helps a bit.
