Fix SVM code B201A - Checking software version management

After performing firmware update in Audi, Seat, Skoda, Volkswagen cars you will get fault code about software management version. To fix trouble code you need to generate and input new key code. Luckily the procedure is simple. Connect with module 5F, go to adaptation, check channel "confirmation of installation change". There&a 4-digit key over there. Just enter your old key into the I&So XORy and it will calculate new key for you. ℹ️ Now replace your old key with the new one and save it. Change will not be visible or even it will not be accepted. But that&OK. This channels value is immediately replaced with the old one. You can tell if the new key is valid by checking if the B201A fault changed its status from static to intermittent. If so you can clear the code. ℹ️ Fault code B201A can appear in many VAG infotainment units. Including, but not limited to: VW Discover Media, VW Discover PRO, Audi MMI MIB, Skoda Bolera/Columbus/Amundsen, MIB1, MIB2... 0:00 Checking B201A static fault 1:03 Rear old key 1:27 Calculate new key 1:57 Enter new key 2:17 Clear SVM fault code
