Hi little roller wheel on right side steering wheel not working is it easy fix ? Thanks 

I've just had mine fixed under warranty. It was not working well from new.

 

Dealer replaced the whole assembly 3v0919719f which includes the buttons on both sides.

Mines a MY19 Sportline 280 4x4. I think the switches vary slightly with graphics.

Mine is MY19, so I have a VIEW button, not a phone button.

 

Had both sets replaced earlier this year under warranty, as they failed.
