Can the GS911 diagnose faulty multi controller wheel?

[MondoRich]

These are known for being troublesome on the R1200GS/GSA and failing. The wheel operates in four directions, rotating up and down and also clicking left and right to control the BMW SatNav. It sits next to the left handlebar grip.

A new wheel is around £140 but is non refundable if not required and it would be great to know you have a confirmed fault before ordering one?

The Autoscan is clear and hasn't detected any faults but im unsure if this switch is being checked.

Any advice much appreciated
