I have configured TFT display into my car by VDASH.
How to activate UP/DOWN SIFT INDICATOR (manual car). At this moment it remains all the time in middle position.
I am not sure, if this model year support this. But you can search in car configuration in VDASH for "Shift indicator", it should be somewhere in Transmission menu item.
VIN YV1BW0551B1XXXXXX
