Filling the fluid looks easy, yet I have not found a DIY on how to bleed the system other than a few comments that it is very easy and self pressurizes. If you find one please post it.
I don't see why you'd need to go to the dealer unless you're unable to bleed the system. The system self-synchronizes, so I don't see why you'd need any programming. If I have trouble bleeding it I'm going to have an independent garage bleed it and verify the top works before reinstalling the rear interior.
