On Board Computer Query

[srad34]

Hi All,
I have a query ref my OBC. ....
It has one fitted (Column Stalk and option code present on bonnet sticker).
The stalk does not appear to do anything, the displays show the following:
LEFT speedo- display shows Mileage/trip
CENTRE tacho- display shows Speed
RIGHT- temp/fuel - display shows Oil level/Clock

The central tacho display is larger so there are additional rows for more data, you can see the fuel icon etc for range.

Are there any common faults with the stalk or specific things to check before I deconstruct the plastic cowling behind the steering wheel?

It would be great to see if I can get it working as the information would be useful.

Any help/guidance would be appreciated.
