ABC Control Module Coding Help

[tbro]

I own a 2003 Audi A4 1.8t Quattro and my ABS Control Module died. After buying another and putting it in I now need to code it.

Here are the steps I take for trying to code it.

Plug in the OBDEleven bluetooth connector. 
Connect the app.
Open the module selection menu.
Open the breaks menu.
Open the coding menu.
Apply the new code which is 5 numbers and something along the lines of 04752 I can't remember the exact numbers.
It says there's an error. 

I've also tried the same process but with the added step of opening the security tab and logging in.
It then says the login is accepted and I try to code again.
I then try to code again and it says the code is accepted however the code remains 00000 and does not change.
When I open the change history logs it shows that the code was changed and it displays the old code and new code.
00000
Changed to
04752
But the code does not change.

I cannot get the code to change and I'm not sure what the issue is. Are there additional steps I need to take before coding the ABS Module?

I've tried to find how to code it online but found little information specific to what I'm trying to do. However, while searching someone mentioned I needed to program my wheel angle sensor before the ABS Module, but this was just a comment on the forum post I found. 

Any help on this issue would be amazing, if any additional information is needed let me know and I will post it.

Here is a nice guide that hopefully helps you out, if you have seen this before, look at the "Notes" it gives special login codes for certain vehicles. I have been struggling getting even just my initial log in code to take. I just now finally noticed that their "notes" call for a different code than i get following theq guide,only by 1 digit. i have not tried this yet, but could explain my issues. Just my $0.02 hope it helps.
