Default Problem with coding after replace Motorola fixed instalation with Bluethoot module

Hello Audi Folks,
I am new in this forum and I want to thank you in advance for your help. I made the exchange from fixed telephone Motorola to BT hadsfree on my Audi A6 4F 2006. So I take the module with part nummber 4F1 910 336B (with SAP) and I made all the wire exactly it was described on this page Audi A8 D3 FAQ point 5.9 (use auto translato to English). The BT module is running now but I have a problem with the coding. I made this coding (please if I made something wrong just let me know):
1. 07 Control Head -> Adaptation 10 -> Channel 12 -> new value 2 -> Save Pic1 Pic2 Pic3
2. 19 CAN Gateway -> Installation List -> CHECK 77 Telephone and UNCHECK Telematics -> Save Pic1
3. 77 Telephone -> Coding 07 -> New coding 0050001 -> Save
4. 77 Telephone -> Adaptation 10 -> Channel 133 -> New Value 1 -> Save
5. From Hidden Green Menu -> Hi Codirung -> APK 0x01, 0x0B ... -> Telephone make -> UHV/BTA -> Accept changes PIC
After all this coding the module is running fine and I pair my iPhone 5 and can use all functions. The problem is when I take out the ignition key and after 5-10 minutes all coding from BT module 77 is gone. When I start the engine and press TEL button on the screen is write "Your Telephone is switched off" and I can't turned on PIC . And the soft codding for 77 Telephone is back to 0000000 PIC ? After that I notice that all field in coding window was fill with nulls (attached pics). I was with MMI soft 2120 and yesterday I update to 5150 (CD1 from 5570) but the MMI don't recognize the BT module. In Hidden RED menu (doesn't have name) only write 0x0103 PIC PIC2 ? And the update don't run on the BT module, just update the another modules but not the BT. After that I tried to update with CD2 (update only for BT module) but again no update for this module. When I try to update to 5570 again no update for BT module. Now I am still on version 5150 and I don't know where is the problem. I attach pictures from VCDS screens and MMI screens that can make it clear the situation. Please can someone help me with this. How I can make codding to be permanent? May I fill all field in 77 Telephone -> Coding 07 -> Soft coding, WorkShop Code, Importer number, Equipment number?

I want to notice that when I go to Hidden Green menu -> TELEPHONE -> FBLOCKS -> on the screen is write "Telephone not yet unlocked!" PIC is there CP for this module? If I check the box "BTA debug FBlock" PIC ?

I want to thank you in advance for your help!!!
