Hi,
I just went through doing the conversion today and want to make sure everything "works" before I get the component protection removed.
Parts:
Aliexpress MIB2 Dynaudio Amp 5Q0 035 456 A
Aliexpress USB/Aux socket + harness 5G0 035 222 E
Ebay 6.5in screen 3G0 919 605 H
Ebay MIB2 headunit 3Q0 035 844
When I turn on the car, the headunit boots into the radio with the "Component Protection" text on screen. The radio will play briefly (1-2 seconds) before the sound cuts out. The radio then power cycles after ~20 seconds. This powercycle loop happens a few times and then it stays off.
Is this normal for the headunit to bootloop a few times?
I also pulled some unexpected codes
U11B800 "Interface for external media (No communication)"
B201A00 "Checking software version management"
Does anyone know if these codes are expected to happen before component protection is removed?
Did the first code mean I didn't install the USB/Aux socket correctly?
Thanks!
The second code pertains to the 6.5" display. The display is a "Slave" unit to the infotainment and while it should work 100% without restricted functionality, it will generate that code until you make an adaptation change in the infotainment unit to reset the "pairing" of the two units.
Here's how:
VCDS CODING:
1) 5F (Infotainment) module, Adaptations, channel: 'Confirmation of installation change'
2) Note your current coding
3) Start Windows calculator and set it to 'Programming mode' and select 'HEX' option
4) Calculation: (current coding) Xor C9D2
5) Change the adaptation channel to the new code (Don't be surprised if it changes back to the original coding, this is normal!)
6) VCDS main screen, 'Auto-Scan'
7) Check for fault codes on all modules and clear the DTCs
Note that VCDS displays your code in 'xx xx' format (small letters and a space character).
You have to remove the space before you calculate your new code.
When you enter your new (calculated) code, insert the space again and use lower cases.
EXAMPLE (don't use these values):
'1a 1a' (original coding of the adaptation channel)
1A1A Xor C9D2 equals D3C8
Enter it as 'd3 c8'
If your original code starts with zero(s) just remove them before calculating (i.e. 0A fb=AFB).
If the new (calculated) code is less than 4 characters, insert zeros in the beginning (i.e. FBB=0f bb).
I had to do this when I swapped out my 6.5" screen for an 8" screen. Again, it's not required, but if you don't like seeing the code pop up every time you scan, this is how you prevent it from happening.
