Oh dear, not seen that before. Do all the dials work, indicator lights on the dash and any warning buzzers like seatbelt warning etc still work?
I'd recommend a diagnostic check to see if any fault codes flag up
I'd recommend you speak to autologics or Audi retrofits as members have used them for retrofits and been happy with the results. I think it would be a case of changing the screen and getting it wired up to the steering wheel controls
