...and another error close to the off ramp...

With point N4 2 here, routing both ways correct

Moving N4 2 just before the off ramp result in routing from east to west incorrect, but west to east still correct.
Seems the node for east to west is not connected here.

Thanks Frans.

I made the custom avoidance on my device just as you have demonstrated. However, there is a problem with the N4 highway in that area. My Garmin map does not show the N4 as bi-directional. It shows that the N4 in that area is only east bound. When I have my custom avoidance enabled, my device will route me via Swaziland and completely avoid the N4. My device would normally navigate me through the off ramp to R104. But the the custom avoidance enabled and the fact that the maps shows the N4 in that middle section as eastbound only, there is no route through the N4 and am navigated via Swaziland.
