Ik ben zelf wat gaan snuffelen op wat vag forums en kwam deze (mogelijke) oplossing tegen voor melding:
"1555 - Check Software Version Management B201A 00 [009]"
VCDS CODING
5F (Infotainment) module, Adaptations, channel: 'Confirmation of installation change'
Note your current coding
Start Windows calculator and set it to 'Programming mode' and select 'HEX' option
Calculation: (current coding) XOR C9D2
Change the adaptation channel to the new (just calculated) code
VCDS main screen, 'Auto-Scan'
Check for fault codes (generated by the update) and clear them (software version, interrupted communication, etc.)
Note that VCDS shows your code on the adaptation channel with a space ('xx xx' format).You have to remove the space before you calculate your new code. At the point you enter your new (calculated) code, insert the space again.
