325 Xpedition, new to me. Base model, no gauge cluster.
There is a switch on the right hand grip for turning on the ‘on demand 4 wheel drive’. No light to indicate when it if engaged.

Originally it appeared that the 4 wheel function did not work at all, but after some use (no idea how long it sat at the dealer) it started working.

Now it certainly does NOT work in reverse, gave it one heck of a work out today.

I ass-u-me that the 4 wheel drive should work in reverse.
Any ideas on how to rectify this?

Thanks!
