Have started to install the dashboard and instruments on the 5 and have got to the rheostat.
The hexagonal 'driveshaft' has a sprung button on it as do all the other controls of that type but the black control knob does not have a hole for the button to spring into.
Is that normal and if so is there any benefit in drilling a hole. Obviously there is no 'pull' action on the rheostat as with the other control knobs?
Many thanks,
Tim
