Hi Lou,
The steering wheel does turn, but the silver/brown part is just not fixed, it's very loose.
On the photo it's indeed the pin circled in blue, but it's for all 4 pins. I can't move the interior assemble more forward, because of the steering cog, which is allready where it's supposed to be. The wire is not in the way and is fitted properly.
Could it be that the black ring on the steering axle is not far enough on the axle, so that the lower part is too long (causing the whole assembly to misalign) and the upper part is too short (causing the steering wheel to fall off constantly).
