Thanks, tnmshd
I checked other screens - no other errors found (in addition to the key drive): https://photos.app.goo.gl/n0YTa21hZnXn6T053
I also checked all the connections, checked 48V coming to the MK4-KD4 through to MK4-MD1. All the lights are on (greens and reds) on all 3 key drive motherboards. Was not able to uncover the one which is right above the pedal unit - need to disassemble all the pedals and handles which left for the last chance.
