Steering wheel controls

[Big G mfc]

Hi folks, my Leon went into the dealer to get a service, update and some issues looked at in particular the right side buttons on the steering wheel wouldn't work. As usual the buttons worked perfectly when they had it and it has been fine for a while, but now it's no longer working again and I'm now stuck with a horrible display in the dash the one with the lane keeping display and a digital speed under it anyone know of a reset without using the buttons?
