dash and steering wheel controls problem...

[julia may carr]

Can anyone help please? My new T6.1 needed battery recharge after standing for Nov and Dec. (Learn't my lesson) . Did that fine but I am left with a Turn on Light notification on the dashboard. That will go if i turn on a light, and then the normal speed etc shows, but the controls on each side of the steering wheel will not work eg I cannot operate radio volume on the steering wheel etc etc. How can I rectify these two issues please? Thanks, Julia
